Reduced testcase

Crashing page: <a href="http://new.bookmyshow.com/">http://new.bookmyshow.com/</a>

Webpage crashes in iOS Safari, as well as other browsers/apps that use the Webview. In Chrome, simply opening the page crashes the whole browser.

I've managed to reduce it to:
<a href="https://dl.dropboxusercontent.com/u/104812/ios-chrome-crash.html">https://dl.dropboxusercontent.com/u/104812/ios-chrome-crash.html</a> 

Seems to involve the ::-webkit-scrollbar-thumb / :window-inactive pseudo selector and SVG.</pre>
