| <title>IsInputPending: pointer locked elements may detect pending input</title> |

| This test should be run under <code>--enable-blink-features=ExperimentalIsInputPending</code>. |

| <p> |
| Verify that input is detected with and without pointer locking for each frame, and that sibling and child frames cannot observe pending input. |
