[whatwg] HTMLForms: Implicit Submission with {display:none} button

[Kaustubh Atrawalkar]

Hi,
There is an issue regarding form submit button which is little unclear from
the specs mentioned in here http://www.whatwg.org/specs/web-apps/cu ...
submission
If the form has submit button with display property as none, will that form
should be implicitly submitted on pressing enter key? This works in Opera &
Firefox but does not work in IE & Safari as of now. What is the expected
behavior for this?

Thanks & Regards
