Automatic update from web-platform-tests BFCache: Make a WPT test work with BFCache If we enable same-site backward/forward cache, backward navigation does not trigger onload event. This CL updates a WPT that depends on the onload event to handle pageshow event and makes it work with backward/forward cache.
