Bug 239655

Originally raise here https://bugs.chromium.org/p/chromium/issues/detail?id=1316314 Reproduction: https://jsfiddle.net/amk221/z3fdtj2y/ When a select box is interacted with using a mouse on a desktop, and that select box is inside a focusable element, then focus stays within that element. This is correct and works fine. The same scenario but run on a mobile device (where select boxes are often rendered differently), causes focus to leave the _container_ element (which it shouldn't do because focus is still on the select box which is a child of the container). I believe this is in correct behaviour and that the two scenarios should match each other.
