           Summary: Whitespace-only values should be considered empty in
                    required form fields

Currently, whitespace value is considered valid during browser-side form
validation according to "required" boolean attribute of a form element.

This is contrary to practices of server-side form validation where leading and
trailing whitespace is usually removed (trimmed) before validation since
whitespace is usually not useful data of any kind.

So, it makes sense to make browser-side validation consistent with good
server-side validation practices:

whitespace-only values should be full equivalent to zero-length value and
should be considered empty too.

Thanks.
