@mmalerba's pending sidenav change might help with this

[mmalerba]

After my change I'd like to switch our docs and demo sites to have a nice mobile friendly sidenav, I can make sure this is fixed when I do that.

Having the similar issue, any hack or fix to overcome this?

[mmalerba]

This issue has been resolved for https://material.angular.io and sidenav docs were updated with a responsive sidenav example in angular/components#7775
