The lifecycle of IPC Actors allows managed actors to outlive their manager
actors; and the former must ensure that they are not attempting to use a
dead actor they have a reference to. Such a check was omitted in WebGL,
resulting in a use-after-free and a potentially exploitable crash. This
vulnerability affects Firefox < 84.
