Bulk edit silently drops tags after the antd Button migration

[chirag-madlani]

Summary

After the antd Button → ui-core-components migration (#30810), a tag selected
in the bulk edit grid is never applied. The import runs and reports success,
but the tag is missing from the entity afterwards.

User impact: silent data loss. Someone bulk-editing assets sets a tag, sees no
error, and the tag simply isn't there.

Evidence

From the Playwright trace of DataAssetRulesDisabled.spec.ts → Bulk Edit Actions
→ Database service:

• The bulk edit does run — both importAsync?dryRun=true (preview) and
  importAsync?dryRun=false (apply) fire.
• Sensitive appears only in a JS bundle and the tag-search response. It
  never appears in the import payload.
• The post-edit screenshot shows the service with empty Tags and Tier.

So the tag is chosen in the dropdown but never committed into the grid cell, and
the CSV is built without it.

Confirmed a regression, not flake

Same shards on #30780 (Typography, merged green) — same pipeline, same seeded
data, one commit earlier:

shard	#30780
data-asset-rules-01	pass (10m56s)
ingestion-01	pass (15m14s)
ingestion-02	pass (17m59s)
reindex-01	pass (19m32s)

They fail on the Button branch consistently across two reruns of the same commit,
and pass on unrelated PRs (e.g. #30469, full 105-check run). One shard,
chromium-01, was genuinely flaky and now passes.

Ruled out (tested, not reasoned)

• Core Button swallows onClick (react-aria usePress stops propagation —
  the fix(ui-core): stop Typography ellipsis tooltip from swallowing ancestor clicks #30804 mechanism). Headless probe: onClick fires, including with
  force: true.
• Core Button defaults to type="submit" — it defaults to "button".
• antd Tooltip wrapping a core Button crashes — renders fine.
• InlineEdit prop precedence — was a real bug (converted props emitted after
  the {...saveButtonProps} spread, clobbering caller overrides) and is fixed in
  refactor(ui): complete antd Button migration to ui-core-components #30810, but it did not change the shard results.

Where to look next

The commit path between selecting the tag and the grid cell holding it —
fillTagDetails → clickInlineSave (inline-save-btn) in
playwright/utils/importUtils.ts, against InlineEdit.component.tsx and the
bulk-edit grid's tag cell editor.

Note the e2e helper clicks with { force: true } because "grid cells and the
fixed import footer can overlap inline editors", so element geometry is worth
checking — core Button sizes differ from antd's (size="small" → xs).

Reproduction

CI only. The dev server cannot render the bulk-edit grid locally (fails at
.rdg-header-row) even though CI gets well past that point, so local repro is
not currently faithful.

Status

#30810 is being merged into antd-migration/wave-1 with these three shards
knowingly red, so the wave is not blocked. This must be fixed before wave-1
reaches main.
