<h1>Pointer Events Capture Test - capture and relatedTarget</h1>
Test Description: This test checks if setCapture/releaseCapture functions works properly. Complete the following actions:
<li> Put your mouse over the purple rectangle. pointerover should be received for the purple rectangle
<li> Press and hold left mouse button over "Set Capture" button
<li> Move your mouse. pointerover should be received for the black rectangle
<li> Release left mouse button to complete the test.
Test passes if the proper behavior of the events is observed.
