They may guess them right, but this one can be checked very easily in
the underlying API: does the browser expose an accessible name for the
input, yes or no? If no (but then the specific AT manages to guess it),
it's still a failure of 4.1.2. That one is quite unambiguous, because
you can't guarantee that all ATs will have the same heuristics.

In the case of misnested/invalid markup, you can guarantee that browsers
all error-correct that markup the same way, since that has been defined
explicitly in the HTML (5/living standard) spec, so not up to heuristics
in browsers anymore, as used to be the case.
