  38       # - It allows for closing many custom dialogs (and perhaps other things
  39       #   -- Esc is a very commonly used key).
  40       # - It is not passed if Esc is used for `command_Esc` and we’re blurring
  41       #   an element. That allows for blurring an input in a custom dialog
  42       #   without closing the dialog too.
  43       # - There are two reasons we might suppress it in other modes. If some
  44       #   custom dialog of a website is open, we should be able to cancel hint
  45       #   markers on it without closing it. Secondly, otherwise cancelling hint
  46       #   markers on Google causes its search bar to be focused.
