--- Comment #8 from Yury Semikhatsky <yurys at chromium.org> ---
I can also reproduce it reliably with booking.com Here is a couple of stack traces on that scenario, they contain WebCore functions which could be used as starting point for further debugging. I'd be happy to help investigating this further but I'd need some pointers from experts what to look for.
