Mozilla Foundation 1527976 0 P2 RESOLVED [Wayland] Dragging and dropping tab outside application windows does not create new window for tab 2020-11-03 19:00:51 UTC

Description rugk 2019-12-23 13:18:36 UTC 
Description of problem:
When you use Wayland (or since Fedora 31, where this is the default), you cannot drag a tab to another window.

Version-Release number of selected component (if applicable): firefox-71.0-15.fc31

How reproducible:
Always.

Steps to Reproduce:
1. Click on a tab and move it it a different window.
2. Drop.

Actual results:
Nothing happens and the "document" icon that moves with the cursor when dropping jumps back to the old window, as if we had selected an "invalid" drop target.

Expected results:
Tab should open in a new window there.

Additional info:
Situations where it _does_ work:
* if you already have another Firefox window opened at the other screen _and_ drop it _at_ that window -> opens as a new window anyway
* same as above, you can also always drop it into another existing window into the tab bar -> opens as a tab
* if you use Xorg, everything works
* (**workaround:**) If you drop the window at the same screen (or choose "move tab" -> "open in new window" in the tab context menu), you can then just drag- & drop the window "as usual".

Fedora 31, GNOME 3.34.2

BTW same happens if you try to drop a link outside of the window.

…and also happens if you try to drag the window _at the screen_ outside of the window.

I.e. it only works if you drag a tab inside of a Firefox window to another Firefox window.

I don't know if that's possible under Wayland as we get a different drag event here. I suspect Wayland send drop cancel in this case.
Comment 3 Jan Rybar 2020-03-14 20:42:13 UTC 
I confirm the bug.
I've used Wayland solely since F29 and everything worked fine.
Cannot remember if this issue has started after update to F31 or recent regular update of Firefox/gnome-shell, but it's started very recently.

This message is a reminder that Fedora 31 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 31 on 2020-11-24.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '31'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 31 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Reproduced in Fedora 33, still a bug.
