<h1>Pointer Events capture test - lostpointercapture order</h1>
<h4>
Test Description:
This test checks if lostpointercapture is handled asynchronously and prior to all subsequent events.
Complete the following actions:
<ol>
<li>Press and hold left mouse button over "Set Capture" button and move a little. "gotpointercapture" should be logged inside of the black rectangle
<li>"lostpointercapture" should be logged inside of the black rectangle after pointerup
</ol>
</h4>
Test passes if lostpointercapture is dispatched after releasing the mouse button and before any additional pointer events.
