seems that a bit of code here is duplicated in the other browser_test file. why
not put them in the same test suite file (i.e. webrtc_browsertest.cc), and have
each test calls a method in the base class with the test file location and
javascript to run?

Good idea, I'll do that. I think I can even merge the tests since the
functionality is related anyway.

nit: better than a comment, add a dcheck. that way the test will fail right away
with a clear message if someone removes that flag

Done.
