Has STR: --- → yes

Seems like a UX edge case. One could argue that our behaviour is perfectly fine (although different from other browsers) because we "prioritize" the selection over the scrollbar. I'll mark this as a P5, I don't think we should spend time on it but if a contributor wants to work on it we could accept a patch.

Severity: -- → S4
Priority: -- → P5
