- We no longer display alternate content for broken images inside image
- We only display the image loading icon during the initial load of an image not if its src attribute is changed via the DOM.
- In AttributeChanged(), se don't call ContentChanged() on the document to reflow the image frame but call the parent frame's ReflowDirtyChild() method instead.
