- Scrolls the page back to the initial point of the target of the corresponding link you selected (i.e. to question, question comment, answer or answer comment) after comment expansion (since also "clicking" on a link programmatically – show n more comments in this case – scrolls the page to that link).
- [internal] Uses regex for
@include and @exclude. (Agreed, this prevents the really nice Sites favicons in Tampermonkey's Installed userscripts tab.)
