We’re using Discourse on the SkySaga forums, and in a thread recently I discovered that Firefox isn’t correctly displaying details tagged things. It works fine in Chrome and Opera (which are my two main browsers) so I hadn’t noticed until a user pointed it out. Weirdly though, the Details tags over on this official Discourse forum do display correctly.
In addition (may or may not be related), I noticed the other day that Spoilers tags aren’t working on our forum. I don’t need help on that (at least not at the moment) and would be happy to investigate that further but the details one is used a fair amount (and I expect it will be used more and more as people learn how to do it) so it not working in a browser that many people use is a problem.
Thread with some details tags to demo this:
