Because the whole page is being validated by Parsoid, sometimes making a reply at one point on the page causes changes elsewhere on the page. These should be investigated to make sure that they are appropriate, proportionate, and consistent.
Whitespace changes that were made
- https://fr.wikipedia.org/w/index.php?curid=3478951&diff=169022495&oldid=169019977 – removes extraneous space in div tag
- https://nl.wikipedia.org/w/index.php?curid=500939&diff=55990506&oldid=55990470 – adds blank line before the start of the list (same list that the reply is in)
- https://ar.wikipedia.org/w/index.php?curid=472301&diff=45591958&oldid=45591951 – removes extra div tag
- https://nl.wikipedia.org/w/index.php?curid=653617&diff=55994380&oldid=55994325 – removes space at end of line
- https://hu.wikipedia.org/w/index.php?curid=258186&diff=22425221&oldid=22425218 – adds blank line. This one matters more than the others, because some archive bots also normalize whitespace before and after section headings, and if they're normalizing it to the opposite style, then the Reply tool will be edit-warring with a bot, which never ends well.
Whitespace changes that were not made
- https://fr.wikipedia.org/w/index.php?title=Discussion_Projet:Aide_et_accueil/Twitch/Sessions/1&curid=13210813&diff=169041994&oldid=169041030&diffmode=source – In the previous comment, there is a space between the list markup and the comment. Why wasn't it removed?
- https://fr.wikipedia.org/w/index.php?title=Discussion_mod%C3%A8le:Infobox_Pand%C3%A9mie&curid=13191551&diff=169260622&oldid=169256883 – One space was removed between the list markup and the start of the comment. Why not one, and not all?
- https://ar.wikipedia.org/w/index.php?curid=1939264&diff=45751794&oldid=45751725 – The space was removed between the list markup and the start of the comment in one line, but not in the next line.
