As an update to this, it seems like the setAutoHide(true) method for
PopupWindows causes this. When excplicitly using setAutoHide(false), the
problem is fixed. Sadly, some skins like ComboBoxPopupControl set this
to true without an option to change this.
I was able to fix this issue by calling setAutoHide(false) when possible
and using reflection to fix the other cases where skins set it implicitly.

It uses a somewhat customized weston wayland setup in kiosk mode to
make it work on the phone screen.
JavaFX applications run fine on it, and the performance is actually
decent. The only thing that does not work are PopupMenus. They don't
register mouse clicks (the events sent are normal mouse events, so no
touchscreen mode here). The system is designed for a touchscreen, so
there are no mouse move events or anything like that sent. Only mouse
button events are sent. When using the actual phone touch screen, it
also only sends mouse button events.
When clicking on any popup menu, it just closes without registering
the click. The only exception when it works is if the parent node of
the popup window is behind the click location. I recorded a video to
showcase the problem. The only time the click registers is at the end
when the button that opens the menu is behind the open PopupMenu where
it is clicked. The "Set default" menu item works one time if it is
clicked right on top of the "..." button, but does not work if the
click location does not hit the "..." button.
If anyone has an idea of what to do with this problem, let me know. I
can test things, I just don't know how one would get started
troubleshooting this issue.
