Comment(by gk):

 Resizing the window in onStateChange() (with a STATE_STOP flag)
 (WebProgressListener) works for me on Linux and Mac OS X reliably without
 the resizing being visible ("xul-window-visible" is broadcasted in
 SetVisibility() in nsXULWindow.cpp which gets called by OnChromeLoaded()
 which in turn gets called in onStateChange() (see: nsWebShellWindow.cpp
 for the latter). Only on Windows the height is still smaller (2px!!, wtf)
 as expected. If I can't come up with a cleaner solution, resizing again
 with setTimeout(0) (still in onStateChange()) might be good enough as I
 doubt increasing the height by 2px once is annoying users. Doing that
 additional resizing with setTimeout(0) might be a good idea in general, as
 a "defense in depth", if the other hackery is still to racy or gets broken
 by some changes in underlying Mozilla code...
