Debugging this. Here's what I'm encountering:

• Begin highlighting off of anchored text
• Highlight into anchored text
• Once the highlight extends into anchored text, the selectionStart/End range from stops updating.

Also, this is not link specific. If you use this with bolded text, it also happens. It seems to be a bug where anytime you highlight text and it crosses into a new tag <a>, <strong>, etc, it stops updating the selectionStart/End values.

I believe this issue was introduced by #47525.

I've been looking at it today, but don't quite understand how it all ties together and what a good fix might be.
