[whatwg] Defines the default size of <input type='range'> and other form controls

[Mounir Lamouri]

Hi,

Currently the specification specifies some form control sizes (at least
text controls and progress and meter elements) but most of the form
controls bindings do not specify the expected default size of the
control. I believe that the default size is quite important for
interoperability, especially for inline-block elements that might end-up
wrapped in text: if the default height is defined in px or em, the
rendering might differ a lot.

I think that it would be great to define default sizes for form
controls, in em preferably I guess.

Thanks,
