Improve primary menu bar - remove need for "overlayForHover"

Should we revisit this after: ✨ Implement the updated insert menu and layers panel Active ?

Surfaced by @jessebaker's review of 🐛 Improve primary menu bar - remove need for "overlayForHover" Closed: outdated .

Linking @lauriii's #2. I doubt @lauriii intended to close this?

Ah good catch @Wim Leers. I meant to postpone this.

Confirmed with @hooroomoo that this is no longer needed after ✨ Implement the updated insert menu and layers panel Active .
