**Steps to replicate the issue** (include links if applicable): * open https://de.m.wikipedia.org/wiki/Fu%C3%9Fball-Bundesliga_2023/24 logged out * resize to a small viewport * watch the infobox behaviour **What happens?**: The infoboxes don't get expanded to full viewport size because since T361589, they get the styling from WikimediaMessages instead of the old template hacks which relies on body.skin--responsive. body.skin--responsive is not activated by default. **What should have happened instead?**: responsive styles should have been applied to the infobox. **Other information** (browser name/version, screenshots, etc.): On the other hand, if a user has responsive skin mode activated, they now always get the full-size infobox independently from the current viewport.
