Had this occur today. Normally when I log in or click on the banner, the editable profile is normal, however, today was a bit different. This jumbled/combined text happens a lot on Twitter, that I have seen, but this is a first here. (Actually happened twice, but I only have this screenshot.)
Browser I currently use: Mozilla Firefox 44.0.2
