web: Your account shows an empty red error box under the handle rename

Oliver's screenshot (prod, account page, att-z4t70ardaabz in his chat with A): under "New handle for your handle @ [field] Rename" an empty, full-width red box (error styling, no text) is shown before anything was submitted. Probably the rename form's status/error element is rendered with its error class (or the error rule styles an empty element) instead of staying hidden until there is a message.
Expected: no box until the hub answers with an error; an empty status element takes no space. Check the other status lines on the account page and the shared status helper for the same pattern; smoke case that an untouched form shows no error box. Small, before the launch; after the hierarchy PR or in between, your call.
