Yeah, the latest update seems to break many HTML tags due to DOMPurify’s heavy sanitization. The sanitization takes place when you preview or edit the card, so fortunately the other ones remain untouched.
I also had similar problems and fixed them by reverting to Anki 24.11, but I hope the next updates will fix this issue.
See my post Anki 25.02.1 removes embedded <iframe> tags and SVG attributes which also links to the relates GitHub issues.
