// This class's data can be accessed via its methods from both the UI and IO

// class, ensure that you avoid introducing any reentrant code in the methods,
// and that you always aquire the locks in the order |web_view_info_map_lock_|
// -> |web_view_partition_id_map_lock_| (if both are needed in one method).
