broken panel visibility during desktopgrid animation
SUMMARY
Since bug 451590 got fixed now (WindowHeap animation stuttering), it's become
more obvious that there's an issue with desktop panels when opening and closing
the desktop-grid.
1. Panels set to auto-hide are incorrectly fading in while closing the grid and
they disappear instantly when the animation finishes (this can only be observed
when no window is maximized). This is the bigger issue of the two, as it makes
the closing animation appear glitchy.
2. Panels which are are always visible don't fade out while opening the desktop
grid. Compared to when closing the grid, the panels correctly fade in. This is
just a minor inconsistency issue.
STEPS TO REPRODUCE
Set the global animation scaling factor to a slow value to properly see the
issue.
1.1. Have a panel added to the desktop and set to auto-hide
1.2. Open desktop grid and close it again on a desktop where no window is
maximized
1.3. Watch the panel incorrectly fade in when closing the grid, even though
it's supposed to stay hidden, and then watch it disappear instantly when the
animation finishes
2.1. Have a panel added to the desktop and set to always-visible
2.2. Open desktop grid and close it again on a desktop where no window is
maximized
2.3. Watch the panel disappear immediately when opening the grid, and watch it
correctly fade in when closing the grid
