Woh, cxrazy this is no pep8, but I guess chromium style with studlyCaps?

Nono, you're right, this should be under_scores:
http://www.chromium.org/developers/coding-style
http://www.chromium.org/blink/coding-style#TOC-Python

This is legacy code and we should fix it up;
I'll do that in a separate CL so this CL doesn't bloat.

Python style (and bug fix!) for this file addressed in:
