This reminds me of #1999#comment:14.
[[Image(thunderbird-popup-focus.png)]]
I can reproduce the problem, but only with the html5 client.

BTW, unless you really need hardware accelerated opengl (does thunderbird even use it?), using vglrun is not recommended as restarting the real X11 server will kill the opengl connection.. it reduces isolation and introduces potential instability.
The default software renderer should be enough.

The bug comes from the DIV z-index calculations.

• the dialog window shows up as:

<div id="4" class="modal wmclass-Thunderbird window window-DIALOG border ui-draggable ui-draggable-handle ui-resizable wmclass-Mailnews windowinfocus"
  style="z-index: 17500; width: 1088px; height: 640px; left: 0px; top: 0px; cursor: default;">

• the popup:

<div id="7" class="wmclass-Thunderbird window window-POPUP_MENU override-redirect wmclass-Popup" style="z-index: 20000; 
  width: 240px; height: 153px; left: 13px; top: 413px; cursor: default;">

So 15000<17500 and the override-redirect popup ends up under the dialog..

Trivial fix in r24932.
