1962452 - Ensure old capture snapshots render in the old display list, to prevent flickering.

The patch currently attached to bug 1959648 doesn't work in the presence of nested snapshots.

It seems it'd be easier for WR, (and not too hard for Gecko) to, on the "old" capture, record the right position and image key, and make a display item hanging off the nsCanvasFrame that pushes all the images at the right position and the right stacking order.

As per further discussion with nical, we might not need to do this after all.
