Bug 1404222 Part 3: Block onload when shape-outside images are requested for a frame, and keep it blocked until the frame is removed or reflow is complete. r=dbaron,dholbert When we finish decoding an image frame, we need to trigger reflow for the frame containing a float with shape-outside: <image>, and delay the firing of the document's onload event until that reflow is complete.
