[ui5-popover]:Block Layer Not Cleaning Up After Dialog Close - `popover="manual"` Issue

[VidhiNPatel]

Bug Description

After clicking Cancel on dialogs, the OpenUI5 block layer (id="sap-ui-blocklayer-popup") remains visible with popover="manual" attribute and blocks all user interactions on the page.

PR #12659 (#12659) introduced popover="manual" attribute to OpenUI5 block layers to fix rendering order issues between OpenUI5 and Web Components dialogs.

The Problem: When dialogs close, the cleanup logic fails to call hidePopover() and remove the popover attribute, leaving the block layer stuck in a visible state.

Expected Behaviour

Expected: Dialog closes, block layer is hidden, page is interactive

Actual: Dialog closes, but block layer remains visible with these properties:

• popover="manual" attribute still set
• display: block
• visibility: visible
• User cannot click anything on the page

Technical Details

Block Layer State When Stuck

<div id="sap-ui-blocklayer-popup" 
     tabindex="0" 
     class="sapUiBLy" 
     popover="manual" 
     style="z-index: 28; visibility: visible; display: block;">
</div>

Expected Cleanup (Not Happening)

According to PR #12659, the cleanup should call:

// From packages/base/src/features/patchPopup.ts
function closeNativePopoverForOpenUI5() {
  blockLayer.hidePopover();           // ← NOT BEING CALLED
  blockLayer.removeAttribute('popover'); // ← NOT BEING CALLED
}
