trying to make a menupopup in xul with alpha (either opacity, rgba value, transparent) computes the background regarding the window background color. it doesn't take care of the window background image or the underlaying elements. idem with the -moz-box-shadow.

tested within menu element in toolbox menubar in firefox 3 & 3.5

Reproducible: Always

Steps to Reproduce:
<toolbox>
  <menubar>
    <menu>
      <menupopup>
        <menuitem/>
      </menupopup>
    </menu>
  </menubar>
</toolbox>

i've tried to inspect linux specific bindings or so, sorry if this is not a real bug. the non-clean joined code works perfectly on windows, background with alpha alpha channel remains on the menuitem elements on linux x86_64

Virgile, can you please try to reduce the testcase to only one file? You can reference an external background image and move the CSS to the XUL file? That would be great.

Virgile, can you please check with Firefox 3.5? I believe that all your concerns were fixed in that version.
