<h1>Pointer Events - lostpointercapture when capturing element in shadow dom is removed</h1>
<h4>
Test Description:
This test checks if lostpointercapture is fired at the document when the capturing node that is in shadow dom is removed from the shadow dom.
Complete the following actions:
<ol>
<li>Press left mouse button over "Set Capture" button. Pointer should be captured by the gray rectangle which is in shadow dom.</li>
<li>Gray rectangle will be removed from shadow dom.</li>
<li>"lostpointercapture" should be received on the document not on the gray rectangle.</li>
</ol>
