MenuItem elements added do not automatically release themselves when dropdown is closed

While investigating https://github.com/overte-org/overte/issues/588 I discovered that when you click on the "Delete" option from the dropdown edit menu, the delete button will never be released unless you interact with something else.

This leads me to believe that there is a core issue in the menu bar that does not release any buttons when the dropdown is closed automatically. As far as I am aware only the Create App suffers from this issue due to how the menu bar is populated and how Create App listens for the "Delete" key being pressed.

I can not confirm this to absolutely be an issue, further testing is required to make sure this is a legitimate bug.

A good place to poke at this is the Create App on line 2142.

We do have other weirdness related to the menu bar, maybe it is related? https://github.com/overte-org/overte/issues/167 If you are on KDE, could you try setting XDG_CURRENT_DESKTOP=foo as environment variable?

Setting the environment variable results in the same behavior.
