I see the same logout behavior. Chrome on Windows 11. When I click the logout button, the page reloads but I'm still logged in until after several (maybe six or so?) attempts. Happened on three occasions, including today.
Incidentally (or not?), when I tried to create a family member's account in the same browser tab I'd logged out from, the circle spun and spun but didn't complete and we didn't receive an email. That was two days ago, and I still can't access the new account with the password. Nothing happens when I enter the email address and click forgot-password, though I can see that the account has a user page with the corresponding cake date and time.
Printing-press typesetters had a rule for how much space should be between sentences. Then people started having personal typewriters that were monospace, so to make their documents look similar to traditional publications and to more easily see the punctuation marks, people would put two spaces before starting a new sentence. Personal typewriters got more sophisticated with better spacing, making double-spacing unnecessary, and then computers came on the scene with word processing software, which also had no need for the improvised double-spacing.
But people had already learned from their teachers back in high school that they should double-space on the typewriter. So they taught it to their students with advanced typewriters and computers, and some of those students to this day just won't quit.
