1172302 - Floating panel level:parent remains in view when parent window is minimized

Status: REOPENED

(Core :: Web Painting, defect)

Description

[u462496]

Attachment: [e-mail]

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 :-)

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.

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.
