okay but once there is a duplicate of that class, it'll continue to happen - so if your preferences were off in the library and you copied/pasted a component there that didn't match, created a duplicate class, and then tried from the extension, it'll also create a duplicate class. We just need to cover our bases here so that we're not flagging a false positive on a bug. Once we have this confirmed, I can try to reproduce the bug - if I do reproduce it, then I'll file it. If I can't reproduce it, then I won't be able to file the bug unless I have hard evidence. Hard evidence would be a loom video or similar showing the bug happening in real time.
