Unfortunately I can't see a change. The css is loaded and appears in the events.css file, so no caching issue.

@chfsx For completeness I would like to add that the 'Beitreten'-Button for Livestream-Publications has the same problem. It is displayed as Text-Link like 'Abspielen'.

I now updated the PR accordingly... My browser was a bit more gracious, the CSS was simply invalid, please excuse!
FYI: the branch was rebased/force-pushed. If you have any questions about how to check out again, please let me know.
