What?

Closes #78726

Removes the header close button from the Quick Edit drawer in the Pages DataView.

Why?

The Quick Edit drawer had two affordances for dismissal: an X close button in the header and an explicit Cancel action in the footer. This created ambiguity — it was unclear whether closing via the X would save, discard, or prompt the user. Having two controls that appear similar but may imply different intent increases cognitive load.

This pattern has precedent in AlertDialog, which intentionally omits a close button to force an explicit decision through the provided actions.

How?

The close button in PostCardPanel is conditionally rendered only when an onClose prop is passed. The fix removes the onClose={ closeModal } prop from PostCardPanel in both Quick Edit modal files:

• packages/edit-site/src/components/post-list/quick-edit-modal.js
• routes/post-list/quick-edit-modal.tsx

The interaction model is now unambiguous:

• Done → save changes
• Cancel → discard changes and exit

Testing Instructions

1. Go to the Site Editor → Pages.
2. Switch to Table layout using the layout switcher in the toolbar.
3. Hover over any page row and click Quick Edit.
4. Verify the drawer opens with the page title in the header but no X close button.
5. Verify Cancel and Done buttons are present in the footer.
6. Click Cancel and confirm the drawer closes without saving.
7. Re-open Quick Edit, make a change (e.g. toggle status), click Done, and confirm the change is saved.

Testing Instructions for Keyboard

1. Navigate to Site Editor → Pages → Table layout using Tab.
2. Focus a row's Quick Edit button and press Enter.
3. Confirm focus moves into the drawer and there is no focusable X close button in the header.
4. Tab through the form fields and footer buttons — only Cancel and Done should be reachable.
5. Press Enter on Cancel to close, confirm drawer closes.
