See this jsfiddle for a demonstration: https://jsfiddle.net/poztin/z2bh145m/7/ The blue box should be scrollable. Collapse the window so that the red box overflows the container. In Chrome and Safari < 10 this works fine. In Safari 10 the blue container is no longer scrollable.

I don't think "regression" in the test name is useful.
