Description

4 months ago
I have a problem with Firefox Beta 53.
Sometimes panels appear in a wrong place.
It happens unpredictably, however, I noticed one specific scenario when it happens

1. Put Downloads button before location bar
2. In maximized window, click on that button
3. Press Win+Left to change window size. Then you can even press Win+Up to restore window size

Result: Only right 30px of the panel are visible (panel is appears in a wrong place).
Expected: The whole panel should be visible.

Happens with all buttons with panels, for example Pocket. Doesn't happen in Firefox ESR 45.

I can see the issue in Fx45.8.0esr, with Win+Right key * 2.

This is not what I did. However, the panel never went off-screen, and that's why this bug is UX regression.

This bug is especially bad in conjunction with Bug 1349096, which is still unconfirmed, watch attached video.
