This eliminates the use of ResourceLoader in HTMLObjectElement. The spec steps around fetching have been slightly updated since we've last looked at this, so those are updated here. Regarding the text test change: we cannot rely on the data: URL being fetched synchronously. It will occur on a deferred task now. This does match the behavior of other browsers, as they also will not have run the fallback representation steps as of DOMContentLoaded.
