1729742 - Window maximize/restore button not highlighted on hover or active

Status: RESOLVED FIXED

(Firefox :: Theme, defect)

Description

[Molly Howell (she/her) (mostly inactive)]

On at least Windows 10 and 11, when the system title bar is not enabled, hovering over the window maximize/restore button does not highlight it. It also doesn't get highlighted while active (i.e., being pressed).

Confirmed via mozregression that this regressed in bug 1718629.

Bug 1729749 may not be precisely the same bug, because the button does still function for me, but it does look like the same regressor.

We will have to handle WM_NCMOUSEMOVE in addition to WM_MOUSEMOVE because the maximize button is no longer a client area.

We have mMouseInDraggableArea to resolve a similar issue (bug 1534389).
