Markdown itself is very old and afaik does not actually support spoiler tags (I don’t think they were even a thing at the time). So every implementation of spoiler tags is just their own cooked up mess.
Lemmy follows CommonMark, which is similar but not exactly the same as what was used in The Other Place. I do wish Lemmy supported some form of in-line spoilers.
eli5 for why the markdown needed to change to be different on lemmy from “the other site”? Is this style markdown more standard elsewhere?
