This was originally added in #1708 which referenced babel/babel#13001 which in turn referenced this Chrome bug. That bug was fixed at the end of March and is supposedly released V8 9.1 (I don't know how to formally check which version a bug was fixed in?) which was first used in Chrome 91.

I'm not entirely sure how this compat table works, if it's all just manually put together. If so, maybe it's time to mark it as a yes in Chrome 91 and onwards?

Finally, for very particular issues like this, is there a way to quickly find the browser bug for it without digging through the web? 😄 Maybe a citation should have been added originally, along with a link to the Chrome bug? Or is there a different way you guys do it?

Appreciate the hard work with this table!
