If you type a comment, then change your mind and attempt to change pages. There's no prompt. So the UI just dies for no reason. Took me a minute to figure out what happened. Wound up refreshing the page.
If I type in the comment field above. Keep the text, and try to click a navigation: midwest.social Communities, Create Post, Create Community. They fail to go. Once I submit (or clear the contents), I can navigate on top again.
Dies was a really bad choice. They are disabled, non-active, when text exists in the comment box. Just verified it here at home on Chrome as well. Going to copy login to Firefox and see there.
