Environment and editor updates
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The sidebar virtualization should reduce rendering cost for large collections, but the current head still has bounded risks: renamed rows may expose stale identity attributes, empty states can briefly disappear after scrolling, and tree-focused tests may target incomplete or incorrect rows. These can cause user-visible flicker and unreliable validation, so the issues should be addressed or explicitly accepted before merge. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
The 300 ms delay is now redundant and re-fires on every remount.
flattenCollection already suppresses the root CTA row while the collection is loading or unmounted (flattenSidebarTree.js Lines 231-236). The flicker this timer guards against is handled upstream.
Virtuoso unmounts rows that leave the viewport. On remount, ready resets to false, so the CTA disappears for 300 ms each time an empty collection scrolls back into view.

areEqual omits the row fields that SidebarRow renders.
The wrapper renders data-collection-id, data-collection-uid, and data-parent-name. The comparator checks collectionUid but not collectionId or parentName.
Rename a folder, and the flattener stamps a new parentName on each child row. The child item object is unchanged, and row.id is unchanged, so the comparator reports equal and the DOM keeps the old data-parent-name. The same applies to collectionId after a collection rename. The E2E locators scope rows by these attributes, so they resolve against stale values.
🐛 Proposed fix
const areEqual = (prev, next) => {
const a = prev.row;
const b = next.row;
return (
a.kind === b.kind
&& a.id === b.id

Do not treat mounted rows as the complete collection.
Virtuoso mounts only viewport rows. getCollectionItemCount, getCollectionTreeStructure, and waitForItemCount therefore return partial results or time out for large collections.
Collect rows while scrolling the virtual list, or expose a non-DOM collection model for these assertions.

Wait for the expansion state instead of using a fixed delay.
The 50 ms delay does not ensure that the next virtualized rows are available. Wait for the chevron state after the click.
Proposed fix
if (!expanded) {
await chevron.click();
- await page.waitForTimeout(50);
+ await expect(chevron).toHaveClass(/rotate-90/);
clicked = true;
break;
}As per path instructions, use auto-retrying assertions instead of sleeps or arbitrary timeouts.

Use a unique parent identity for flat-sidebar child scopes.
data-parent-name is not unique. Two collections, or two separate folder branches, can contain the same folder or request name. These helpers can then click, expand, or assert against the wrong row.

Wait for the virtualized collections scroller before resetting it.
Virtuoso exposes sidebar-collections-scroller, but count() does not wait for it to mount. The fallback can select the wrong element, and optional chaining can skip the reset. Use the explicit locator with waitFor({ state: 'visible' }), then call scrollTo() without optional chaining.

Description
Virtualizes the collections sidebar so it renders only the rows currently in view instead of the entire nested tree.
It keeps render cost flat no matter how many collections, folders, requests, or examples exist.
Added the missing tests here #8891
Problem
The old sidebar rendered the collection tree recursively so every collection, folder, request, and example are mounted even though they are not in the viewport Rendering cost scaled with the total number of items, so large collections were slow and heavy.
Benefits After Refactor
Fix
Used virtuoso to virtualize the sidebar items. Since virtuoso works on flat data, we are flattening the sidebar nested data and feeds it to virtuoso. Now the rows which are currently visible on viewport are mounted and in the DOM. Also added a overlook scan to avoid a flicker on fast scroll.
This fixes problems with slow typing in Editors, codemirrors whenever user have large number of items in the sidebar.
Used four maps to store the data and for fast lookup
The object maps: itemsByUid / collectionsByUid: These map a uid to the live folder/app/request or collection object in the Redux store.
Rows are structural only, a row carries id, kind, depth, uids, sortName, parentName, but not the actual object. Since Rows are rebuilt on every flatten, and if each row embedded the full item object, then (a) rows would be fat, and (b) memoization would be hard.
The index maps: rowIndexByItemUid / rowIndexByCollectionUid: These map a uid to the row's position (its integer index in the rows array), and they exist for exactly one feature: scroll-to-active-tab.
Changes
utils/collections/flattenSidebarTree.js: This contains the functions to flat the sidebar nested items.flattenSidebarTree: This takes the nested sidebar items and returns a flat row containing all items.flattenCollection: Adds a collection and its visible children to the flat sidebar row list.walkChildren: Flattens the children of a collection or folder into sidebar rows.Sidebar/Collections/index.js: This used theflattenSidebarTreefunction and feed the flat rows toVirtuoso.It renders the rows using
SidebarRowcomponent.SidebarRow/index.jsx: This renders the items using theitemsByUid, collectionsByUidmaps. Based on the kind of row item it maps them to the right presentation componentCollectionRow, CollectionItemRow, EmptyCtaRow, ExampleItem, GitRemoteCollectionRow).slices/collections/index.js: Since Virtuoso unmounts offscreen rows, per-row "examples expanded" React state wouldn't survive a scroll. Added the toggleRequestExamples reducer and an examplesExpanded flag on the item so expansion state lives in the store and examples are emitted as their own flat rows.Test-side changes: the DOM is now flat, every helper and spec that relied on nesting (.locator('..'), #collection- descendant scoping) was rewritten to scope by data-collection-id/data-parent-name.Screenshots
