I may have lost track of the plot here - but I didn't think you were adding the
named getters in - I thought you were exposing query operators?

[Emily Fortuna, 2014/08/06 00:32:26]

Query is part of the getters. That's how it's exposed, through the named
getters.

This will break if checked in - not a problem with your changes, but you'll need
to work around it.  This CL  https://codereview.chromium.org//395913002 seems to
have deleted this from the idl, but not updated blink (and doesn't work if blink
is regenerated).  This should get fixed soon, but in the meantime, you might
want to just hand add this back in before checking in.

Why is this showing up here - this doesn't seem related to your changes?

[Emily Fortuna, 2014/08/06 00:32:26]

It is related because these members also have union return types which were
previously getting omitted.
