Third sentence of the URL. The last letter (number) of a hyperlinked word (H.263v2) is not part of the hyperlink.
"Filters fand sich jedoch schon im Standard [[H.263]]v2" it's not designed to be by the look.
Numbers are never part of the linktrail (the part after a wikilink). Please user [[H.263|H.263v2]].
