Subject: [PATCH] LibWeb: Pageshow event dispatched by the user agent should be
 trusted

The spec says that "isTrusted is a convenience that indicates whether
an event is dispatched by the user agent (as opposed to using
dispatchEvent())"

But when dispatching a pageshow event the flag was incorrectly set
to false.

This fixes https://wpt.fyi/results/html/syntax/parsing/the-end.html
