Too much indentation, and it seems to be more at enwiki than nowiki, which is really weird! Perhaps nowiki didn't get an update? At nowiki we are missing this bug and feel neglected!
Is it some work-in-progress that got rolled out in a half-done state?
Also note w:en:Wikipedia:Village pump (technical)#Problem with watchlist display.
Bug at enwiki
Less buggy nowiki
