And YouTube. And Search. Hangouts, Gmail, Maps, Calendar, Groups, everything else? I don't buy it for a second that it isn't on purpose, even with the polyfill justification.
You only make it easier for people like me to continue ignoring Chrome (if I even needed more reasons).

But I can scroll through list of clickable and readable tabs if they don't fit the screen all at once, unlike in Chrome where you get lots of unusable hair-thin controls instead.

* Performance is really not that good. I especially have issue on Google sites (Docs and Drive).
* Scroll-wheel to switch between tabs is gone.
* No multi-tab management (shift/ctrl+click to select and move multiple tabs) like Chrome has
