I will also note that there are three patterns when I post a comment that may or may not be related:
it just publishes when I hit the button
I hit the button, it thinks for a second, and then the button is intractable again. Pushing it again works so far in every case (i.e. it seems something goes wrong but no UI error. I haven't had dev tools open to see what happens there. This feels like it took to long for me to reply in some cases, but not all).
I hit post and get moved to a new page which is just my post with a preview. I'm not sure if this is just how it works with certain sites or something or also related.
