Menus in `MenuBar` don't open anymore without a click

Hello! I just updated to 0.32 and refactored various things as needed, but I have a new issue that I can't find a fix for.

In the past, the currently open menu followed hovering over the menubar (the usual behavior on must GUIs), now I need to click another menu button for it to be revealed.

Please see the following video:

I don't think this is by design, but if it is, is there an API to revert to the previous behavior? Thanks...
