What?

Fixes a focus management regression in the "Create pattern" dialog opened from the block toolbar Options menu.

Closes #78952.

Why?

When pressing Escape (or otherwise dismissing the dialog without saving), focus was lost because the onClose handler for CreatePatternModal called closeBlockSettingsMenu(), which closed the entire parent dropdown menu. This left no visible focused element in the page.

Other dialogs in the same Options menu — Lock, Rename, and Hide — all follow the correct pattern: they only close the modal on dismiss, keeping the dropdown open so focus can return to the triggering menu item.

How?

Removed closeBlockSettingsMenu() from the onClose handler in PatternConvertButton.

closeBlockSettingsMenu() is still called correctly in handleSuccess() after the user successfully creates a pattern, ensuring the dropdown closes after a committed action.

 onClose={ () => {
     setIsModalOpen( false );
-    closeBlockSettingsMenu();
 } }

Testing Instructions

1. Create a post, add a Paragraph block.
2. Click the block toolbar Options (⋮) menu.
3. Click "Create pattern" — the dialog opens.
4. Press Escape — the dialog should close, focus should return to the "Create pattern" menu item in the still-open Options menu.
5. Verify the same behavior still works correctly for Lock, Rename, and Hide (they should be unchanged).
6. Also verify: creating a pattern successfully still closes both the modal AND the Options dropdown.
