An essential part of my workflow is to tear tabs off to other monitors. This works fine most of the time. However if I attempt to tear a tab onto my monitor with discord maximized onto it, it simply will not detach from the window. Minimizing discord will let me tear it off. To take it a step further if I un-maximize discord and attempt to tear a tab over discord, it does not work. But tearing it off with my cursor over an area on the same monitor that isn't discord, works fine. This still occurs even with all addons disabled.

This seems to be a problem only with firefox and discord, I can tear tabs off over all other programs on my computer but not discord. And tearing tabs with chrome and edge work just fine. I suspect this might be firefox attempting to send data to discord when it is just detaching tabs.
