Unable to reproduce in 53.0.2785.116 and 55.0.2873.0. Please send a crash id (chrome://crashes).

Sorry - you said the tab is freezing, not that you got a crash. What does "tab freezes" mean, exactly? Is the browser non-responsive? Can you take a sample using chrome://tracing, and one using the JavaScript developer tools?

Thanks Shrike I'll get you that info. Yes tab freeze means that the browser became unresponsive. Also please see my comment with the note that we pushed a fix to our site that detects User Agent and handles traffic from Chrome 53.0.2785.116 differently. Therefor to accurately reproduce, you may need to spoof the UA as something else. It generally crashed around the time there was a CSS animation, fwiw.

Was able to repro in 53.0.2785.116, but not in 55.0.2873.0 spoofing as a Nexus 7 (which is on Chrome 48) via Dev tools. Not sure how to use chrome:tracing, but if the default settings are fine (selected the 'Web Developer' checkbox), have attached a trace. Specific repro instructions: 1. If on Chrome 53.0.2785.116, open DevTools and click the phone icon (second icon on top-right) and select the presets for a Nexus 7. Keep DevTools open as closing them will revert any changes to the UA string. 2. Click 'Add to Bag' on any product. A menu pops out from the right and the tab becomes non-responsive. Task manager shows the tab going up to ~100% CPU and it has to be killed manually. Probably needs a bisect since it's working again in Chrome 55? Tagging with Needs-Bisect.

This is probably a duplicate of crbug.com/644450 , which is now fixed in all branches. This bug doesn't reproduce for me on ChromeOS running version 53.0.2785.129. Please let me know if the problem is now fixed.

Thanks all. I have not been able to reproduce in version 53.0.2785.143. I think it is fixed and was indeed a duplicate of crbug.com/644450 .
