I'm noticing that validation errors listed on the Invalid Page screen are in reverse order from how they appear in the document. A validation error with meta viewport is at the bottom of the list, and the validation error for a custom script in the page is appearing near the top of the validation error list. Nevertheless, a CSS validation error is appearing before, so I think it is an issue with how the whitelist sanitizer is iterating over the DOM backwards. In particular, array_pop() is being used instead of array_shift() in:

Switching these around fixes the problem.
