I went to use a strikethrough for a reply and it didn't work. Then, I tried to embolden and italicize some text and they also didn't work. Not sure what 'title' does, but 'insert link' worked fine. The quote button is broken, also, yet the > quoting method works fine. I'm on Vivaldi, if that helps narrow down what the problem might be. Went to make a spoilered joke about me being an idiot and then it also didn't insert into this post just now. Fugggggg
