1605717 - Linux Wayland: Dragging tab/link outside of window is impossible

Status: RESOLVED DUPLICATE of bug 1527976

(Core :: Widget: Gtk, defect, P3)

Description

[rugk]

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 whole 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.
