#9Mouse drag and drop (DnD) doesn't work in some applications

Example for Mozilla Thunderbird:

  1. Left click on an email in the email list view

  2. Drag towards the folder list view

Outcome: Mouse focus is lost when the mouse starts to move. The effect looks like the email starts to be dragged but then released immediately.

Expected: Email is dragged/moved towards the email list view and effectively moved to the selected folder when releasing the left button

Workaround: mode-enter-input-grab, perform the action above, then exit mode-enter-input-grab

Added notes: Works on Sway as expected

Other applications:

  • Pidgin: DnD in the contacts view (used to group 2 contacts of different messaging services into one line) doesn't work at all, similar to Thunderbird, same workaround can be utilised.

  • Firefox: DnD works in most places, but this issue can be reproduced similarly by clicking the back arrow (to go back in history), keeping it clicked so that the list of websites visited is displayed; then moving the mouse down - the focus doesn't match the arrow. Workaround for Thunderbird doesn't apply here, so feedback as to whether other people can reproduce this would be appreciated.
