I just checked, but I cannot reproduce - and it is unlikely the plugin is the cause, as I am not overriding default editor behavior here. Are you on windows 11 by any chance? I noticed that with recent windows updates there seems to be a copy/paste bug that occurs after long sessions. It should happen across all apps, though.
Some people report this as a “sticky key” issue (which in my case is very likely, I dropped a fresh can of dr pepper on my keyboard at least a handful of times). A restart always fixed it for me though.
