It was used to happen to me with any source, including Notepad or duplicating code within the editor. I usually use chrome, I tried on Edge and Firefox only once as a test.

Kirkburn replicated the issue after asking me to send a video of it, so I won't be surprised if that's the reason they disbaled the editor. The biggest problem about it is with users or admins who don't even realize the issue and end up with broken code.
