chips: can't edit chips mobile devices

[matew17]

I cannot edit md-chips on mobile devices

• when I try to modify md-chips on mobile devices it doesn't work, I tried on iOS and android devices and both have the same behavior.
• What is the expected behavior?: I should be able to edit the md-chips on mobile devices.

We don't need a code pen, you can go to: https://material.angularjs.org/latest/demo/chips
on a mobile device and try to do it, and it doesn't allow.
