Test Description: This test checks that the pointercancel (and if needed lostpointercapture) is dispatched when drag starts.

<li>Press down on the black square.</li>
<li>Move your pointer to purple square and release.</li>
<li>Repeat the first two steps.</li>
<li>Repeat the first two steps once again.</li>
<li>Repeat the first two steps once again.</li>

Test passes if the proper behavior of the events is observed.
