domgood first issue
Description
See https://github.com/whatwg/dom/commit/b8a8eb272d1ff3c654b3c5ae690c990f1d0cd700 for context.
In particular http://w3c-test.org/html/syntax/parsing/the-end.html could be updated to check that load does not dispatch on document (while that is the target override) and that eventPhase is 2 (AT_TARGET).
