In #21382 the preventDefault call was moved further down so it doesn't prevent events until the dragging threshold has been reached. The problem is that it'll only start calling preventDefault from the first event after the threshold has been reached which can be enough time for the device to start scrolling.

These changes add an extra call as soon as dragging has been considered as "started".

Fixes #21749.

In angular#21382 the `preventDefault` call was moved further down so it doesn't prevent events until
the dragging threshold has been reached. The problem is that it'll only start calling `preventDefault`
from the first event __after__ the threshold has been reached which can be enough time for the device
to start scrolling.

These changes add an extra call as soon as dragging has been considered as "started".

Fixes angular#21749.
