@Tatyana-Kravchenko I'd say there is no need to limit teachers with such rule. It's a rare case, but why not? I think it doesn't affect anything.

By the way, it'd be 400 code, not 403. Forbidden is about access rights: https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/403

@Tatyana-Kravchenko "Unexpected behavior" doesn't add any useful information. It's obviously unexpected because it's a bug, right? :)
