nit: Maybe this flag would be more clear if it were named
"set_was_ignored_by_handler".  Then, when you inspect the property on
ResourceRequestInfo, it'll be a function call named "WasIgnoredByHandler."  That
should help people understand that the request is being ignored by the
downstream consumer, etc.

Great naming suggestion! Thanks!
