In Safari it works.

Start with the Angular Material checkbox examples and reproduce the shift-click behavior in Chrome using the versions listed in the issue. Trace the checkbox interaction handling to determine why only the ripple appears; done means shift-click marks the checkbox as expected without regressing ordinary clicks.
