Hi, Sergey-

I have changed the DOM3 Events spec [1] to make the useCapture parameter 
of add/removeEventListener optional.

As Garrett Smith suggested, I have also added an authoring note that 
omitting the 3rd parameter may cause problems in older browsers.

Please let us know whether or not this satisfies your issue.
