For example, http/tests/images/jpeg-partial-load.html, which tries to partially-load a JPEG, does not work in WKTR.

They work fine in DRT. It seems like WKTR cancels the image load on completion, and the snapshot is taken *after* the result of this cancellation appears on screen.

Also we never noticed because we don’t run pixel tests.
