@JBCodingHash I really appreciate you for testing the PR! However, I would suggest commenting on the PR directly instead of making a new issue because we could've missed this really :) I'm closing this since the PR hasn't been merged yet.

Hey @JBCodingHash ! Could you please share us the minimal setup so we could replicate the bug? Thanks!

Hello
Okay, I see. I have to say, though, that it isn’t working for me either, as my last attempt was a while ago and, strangely enough, jsfiddle.net is empty. So we’ll have to leave it at that for now, and I’ll test it again once the other bugs have been fixed.
