@fsackur Sorry that this issue and #1993 slipped off my radar. I didn't realize the "copying to system clipboard" functionality had been always broken. I submitted the fix #3937, the artifact produced from CI can be found here. Please give it a try.

I confirm the fix works on Fedora 39. Thanks @daxian-dbw for this, and for all the other work you do for us.
