This query represents a user's choice to allow or deny access to "powerful features" of the
platform, as specified in the [Permissions W3C
Specification](https://w3c.github.io/permissions/).
When signalled by the #WebKitWebView through the query-permission-state signal, the application
has to eventually respond, via [webkit.permission_state_query.PermissionStateQuery.finish], whether it grants,
denies or requests a dedicated permission prompt for the given query.
When a #WebKitPermissionStateQuery is not handled by the user, the user-agent is instructed to
prompt the user for the given permission.
