fix(ngClick): prevent soft keyboard from disappearing on input click

Currently ngClick calls blur on all elements and this causes keyboards
on touch devices to bounce and sometimes not appear. This is a fix
for #11358 and should allow input fields to keep the keyboard visible
without bouncing in and out of view or never appearing.

Closes #11358
