575725 - sizemode attribute is bogus in popups (always inherited from parent window)

Status: RESOLVED DUPLICATE of bug 610057

(Core :: XUL, defect)

Description

[Dão Gottwald [:dao]]

browser.xul persists the sizemode attribute on the <window> node, which causes popups to inherit the sizemode -- the bug is that this attribute sticks around even though it doesn't reflect the window's actual size mode.

STR:
1. maximize the browser window
2. load http://www.popuptest.com/goodpopups.html, click "Good PopUp #1"
3. using DOMi inspect the popup's chrome document and find the <window>'s sizemode attribute

Expected result: the attribute should be set to "normal"

Actual result: the attribute is set to "maximized"

With bug 571660 and probably bug 588764 making use of this attribute to give the window a custom border on Windows with Aero glass, this bug becomes visible to users. 
Windowed popups opened from a maximized windows lack a border, and fullscreen popups from a windowed page show an unwanted border on the edge.
