🐛 FIX: Linkify link nesting levels

[hukkin]

It seems to me like linkify link tokens have incorrect nesting levels. This PR fixes that.

This seems like a bug inherited from upstream. I'll make a quick PR there as well. EDIT: On closer inspection this seems like a porting issue, so not making an upstream PR.

thanks @hukkinj1
Hey @tsutsu3, since you wrote this code, perhaps you want to comment if you see any reason why this should not be case?

[tsutsu3]

As @hukkinj1 pointed out, it is a porting error 🙏
This fix is correct
