User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:70.0) Gecko/20100101 Firefox/70.0

Steps to reproduce:

1. Click and begin dragging a piece of content (i.e. bookmark via favicon; selected text; image)
2. While holding down the mouse button, attempt to use a keyboard shortcut to switch to another application to drag the content to (i.e. Alt-tab for app switcher; Ctrl-Alt-Right for workspace switcher)

Actual results:

Alt-tab: nothing
Ctrl-Alt-Right: mouse cursor stays in place; dragged content oddly jumps to the right (or left/up/down depending on arrow key pressed)

Expected results:

• Mouse drag should continue "holding" the content throughout
• Keyboard shortcut should successfully switch to other application/workspace
• Drag operation should then be able to be completed to drop the content into another window (on the new workspace, or brought to front via alt-tab)

Also reproduced on Manjaro XFCE

Hi mdmayfield,

Thanks for your report.
I was able to reproduce the behavior described on Ubuntu 18.04.2 LTS.

• Nightly: 72.0a1 (2019-11-04) (64-bit)
• Beta: 71.0b6 (64-bit)
• Release: 70.0.1 (64-bit)

When I drag an image with the mouse, select an image or a bookmark, and press any shortcut such as Alt + Tab, shortcut function is ignored.

I'll go ahead and mark this bug as new and add a product and component.

Regards,
