Created attachment 8616432 [details] email@example.com With a xul:panel with `level` attribute set to `parent`, when minimizing the parent window, the xul:panel remains in view. Expected behavior: The xul:panel should be hidden when the parent window is minimized. Regression: 2013-05-01-03-10-41-mozilla-central - good 2013-05-02-03-09-39-mozilla-central - bad Attaching xpi to demonstrate the effect. To demonstrate, install the addon, Go to Tools menu, and click the item, "Floating panel - level parent". After the panel appears, minimize the parent window and observe that panel disappears in the "good" regression, but remains visible in the "bad" regression.

Me jumping up and down here, wondering why this bug has gone so long (5 months) without attention. It adversely affects All Tabs Helper; I have sort of a workaround but it is not always successful. Thanks :-)
Hi Allasso, Requesting more information. What platform/OS did you encounter this bug? Thanks!
Confirmed on OS X, however I believe the user who reported it to me was using Windows.
Triaged as Layout: View Rendering as we are cleaning out the Untriaged list. If you feel this is the wrong component for the bug, please triage to the correct component. Thanks!
I can't reproduce this on windows 8.1. The panel also disappears when I press the minimize button with all three options.
This bug has been tagged for regression and or closure. Fixed: I cannot produce the error in Nightly or Release Considering this I will mark this issue as Resolved-WORKSFORME. If anyone can still reproduce it, feel free to reopen the issue and provide updated steps/links.
(In reply to Gingerbread Man from comment #1) > Push log > http://hg.mozilla.org/mozilla-central/ > pushloghtml?fromchange=02aa81c59df6&tochange=70e0955ccc87 Guessing this was caused by bug 851641 http://hg.mozilla.org/mozilla-central/rev/3ff6533160bd
Can you confirm if the bug is fixed?
Not fixed. I still have the same result in Nightly 49.0a1 (2016-05-16), OS X. The panel initially animates to the dock with the browser window, then suddenly re-appears on the screen once the animation completes.
Comment 10: Tested using the attached xpi.
Windows 8.1 good, I can produce in Mac OS X 10.11 Version 49.0a1 Build ID 20160517030211 User Agent Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:49.0) Gecko/20100101 Firefox/49.0
