I think the "each the" form is not correct in English, as "each" must
generally be used as in "each one of", or "each of", forms that should
not be used here either as the countable aspect is already expressed
by "each field" further in the phrase anyway.
You're right that it was wrong before, but now it's still a bit odd - we have `each HTML... for each field`. What would be perfect is actually removing the first `each` and leaving `the`:

>
that help you render the HTML widget, label and error for each field

Thanks for your attention to this! It definitely sounds plain wrong the way it is currently :).
