Current behavior:
Sometimes input directives model (viewValue) is not updated when typing to input field.
Expected / new behavior:
viewValue and input value are same after typing.

Minimal reproduction of the problem with instructions:
Sometimes input directives model (viewValue) is not updated when typing to input field.
This occurs with fast typing and slow computer.

This happens because in IE, angular listens keydown -event and has timeout handling that skips new keystrokes if handling of previous keydown is ongoing.
And previous ongoing keydown handling reads old value of input because the value is not updated immediately when key is pressed down.

AngularJS version: 1.6.6

Browser: IE 11
