`BubbleMenu` can be stranded if menu action does not return focus to editor

Affected Packages

extension-bubble-menu

Tiptap Version

3.31.3

Browser Used

Firefox

What happened?

When focus moves from a BubbleMenu to someplace outside the editor, the BubbleMenu is left open and "stranded". This can happen when a button in the bubble menu does not immediately return focus to the editor (e.g. it opens a dropdown).

Expected Behavior

I expected the BubbleMenu to close once focus left the editor.
