| <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. "gotpointercapture" should be logged inside of the black rectangle |
| <li>"lostpointercapture" should be logged inside of the black rectangle after a short delay |
| </ol> |
| </h4> |
| Test passes if lostpointercapture is dispatched after releasing the mouse button and before any additional pointer events. |
