/*
  Bug fix: several components set their own `display` (`.notice { display:
  flex }`, `.field { display: flex }`, `.btn { display: inline-flex }`,
  etc). Author stylesheet rules always beat the browser's built-in
  `[hidden] { display: none }` rule, regardless of specificity — so
  without this, setting `element.hidden = true` on anything carrying one
  of those classes silently does nothing. This one rule fixes it globally,
  for every current and future case, instead of patching each component.
