[whatwg] Drop tabindex=""

[Benjamin Hawkes-Lewis]

Dropping tabindex /might/ make sense if HTML5 was to be so feature
complete that no-one would ever build a DHTML widget out of generic
elements ever again. Is this likely to be the case? Because, if not,
tabindex looks like part of a solution:

Of course, we might want to try to improve on tabindex and fix the
scoping problem. Perhaps:

<div id="foobar">
<div tabgroup="foobar" taborder="2"/>
<div tabgroup="foobar" taborder="1"/>
</div>
