440825 - Unable to place any XUL elements in front of a menu

Status: RESOLVED WONTFIX

(Core :: XUL, defect)

Description

[Mike Kaply [:mkaply]]

There is currently no possible way to put a XUL element in front of a menu popup. 

An example of where this might be useful is a panel popup when hovering over a menu.

I'm not sure what would need to change to make this happen, but at a bare minimum, this code in xul,css is silly:

popup,
menupopup,
panel,
tooltip {
  display: -moz-popup;
  z-index: 2147483647; 
}


We can at least make the z-index a little lower so a window could potentially be put in front of it.

Note I've experimented with a lower z-index in this file and that doesn't solve the problem, but it is probably a start.

Any opinions on this? I just ran into it again trying to do a popup keyboard but it gets overlaid with an autocomplete popup.
