Now we have floating panels in Gecko, I hit a small issue : if two floating panels are visible on screen AND overlap, how do you raise the deepest in z-order??? There seems to be no method to raise a panel above the others. focus() does not help, moving the panel in its parent's child list hides the panel, I found no method for that in the interfaces. The only workaround I found is to hide and show again the panel but that introduces a bad flickering. Help !
