This came out of a review comment for bug 32260. The new function DOMHTMLInputElement::isAutofilled has an assertion with two clauses that would be better split into two assertions. This is true for the other functions in this interface as well.
Created attachment 44471 [details] Patch to split two-clause assertion into two assertions, in new isAutofilled function and friends
style-queue ran check-webkit-style on attachment 44471 [details] without any errors.
