Removed.

nit: Since you're making the same AtomicString each time, might as well use
DEFINE_STATIC_LOCAL to make it fast:

DEFINE_STATIC_LOCAL(const AtomicString, google, ("google"));

[adithyas, 2017/01/09 15:40:02]

Done.

super-nit: the spacing of these lines is a little strange. Is the choice
significant, or could this be collapsed?

[adithyas, 2017/01/09 15:40:02]

Fixed :)
