SUMMARY

Panels are hidden in overview mode. If a panel is set to autohide, however, the highlight that happens when the cursor is at the screen edge still happens once each time the overview is opened. As the panel wouldn't show anyway, it probably shouldn't highlight, as that's just visual noise.

However, the panel invisibly does get shown, and at least sometimes (I didn't notice it every time, but I might have missed it or it might be an interaction with the hotcorner I used to enter overview mode) can get temporarily stuck in an open state.

STEPS TO REPRODUCE
1. Have a panel set to autohide at a screen edge (for best effect, place the panel not adjacent to any overview mode hotcorner)
2. Open overview with a hotcorner or Meta+W
3. Push the mouse against the screen edge with the panel
4. Move the mouse far away from the panel and exit overview with Esc (or a distant hotcorner)

OBSERVED RESULT

After 3: Screen edge glows briefly, but nothing else happens
After 4: Autohide panel is visible and stays visible until you mouseover

EXPECTED RESULT

After 3: No screen glow
After 4: Ideally no panel visible, but at least it should still autohide on its own.
