<h1>Pointer Events Capture Test - capture should not be lost early</h1>
<h4>
Test Description: This test checks if setCapture/pointerup functions
works properly. Complete the following actions:
<ol>
<li> Put your mouse over the red box
<li> Press and hold left mouse button. Box will call setPointerCapture
<li> Press right button and release
<li> Pointer capture should not be lost
<li> Press right button again and release
<li> Pointer capture should not be lost
<li> Release left mouse button. lostpointercapture is called
</ol>
</h4>
Test passes if the proper behavior of the events is observed.
