221625 - Window position not restored correctly after sizing from top/left

Status: RESOLVED DUPLICATE of bug 1753836

(Core :: XUL, defect)

Description

[Dan M]

Windows OS: Resize the browser window by dragging the top or left borders. Quit
and relaunch. The first window opened is sized correctly, but its position is
incorrect: it's unchanged and it should have been changed.

When a border is dragged, Windows doesn't send us a WM_MOVE event; only
WM_WINDOWPOSCHANGED. The current WM_WINDOWPOSCHANGED handler makes note of only
the new size, not the new position, assuming a WM_MOVE is on the way. Losing
that assumption will fix the problem but causes a bit of inefficiency and risks
infinite recursion as the movement feeds back on itself. It's fixable but minor
and a little dangerous.

This bug is what remains of morphed bug 86955, now properly unmorphed and closed.
