   The hidden attribute must actually hide

   `[hidden] { display: none }` is a user-agent rule, so any author rule that
   sets `display` on the same element beats it. `.alert` and `.field` both use
   `display: flex`, which meant every `<div class="alert" hidden>` in the
   codebase rendered anyway — the JavaScript set the attribute correctly and
   nothing happened.

   Found in Phase 13 on the expense form, where a warning about recharging to
   tenants stayed on screen after the choice moved to the landlord. There was
   already a one-off fix for `.tab-panel[hidden]`, which was the same bug
   patched in one place rather than solved.

   !important is warranted here: `hidden` is not a style, it is a statement
   that the element is not currently relevant, and nothing should override it.
