There are a long list of conditions under which the HTMLObjectElement is to queue an element task to load / determine an object's representation. This handles the case where the data attribute has changed. Much of the spec for determining the object's representation is not implemented here. Namely, anything to do with XML documents or browser plugins are left as FIXMEs.
