Hate to tell you my security questions are up to date and still see it so not convinced that's the issue 😉
I'm also administrator on the account in question.
I haven't been in "general" for a few days and just saw your message trail. I have been having the same issue, it's been driving me crazy! Buttons end up being shunted up the page half or completely hidden.
Thanks for digging through the DOM though, I just search that element now if it messes me up and delete it 😄
