[whatwg] [WF2] Label with empty for attribute

[Simon Pieters]

Hi,

It is not defined what should happen when a label has an empty for="" 
attribute. Consider the following example:

   <label for="">foo<input></label>

Is the label element part of the .labels DOM attribute for the input? What 
should the label's .control DOM attribute return?

Regards,
Simon Pieters
