List of steps to reproduce (step by step, including full links if applicable):
- Visit https://www.mediawiki.org/wiki/Extension:TimedMediaHandler/VideoJS_Player#Usage in private browsing mode
- See if new <figure> thumb syntax is enabled for you
- See CC and runtime labels really wide:
What should have happened instead?:
figure[typeof~="…"] CSS needs fixing to stop triggering on random elements inside a <figure>. This is why CSS authors use classes, and why the old thumb layout actually used classes. Please just use classes instead, or even data attributes if this is some unexplainable author preference.
Caused by T51097: Use figure and figcaption HTML5 elements when possible (I don’t know exact project for this work, sorry, so I chose Parsoid for simplicity)
