<div>
<pre>The test at media/modern-media-controls/pip-support/pip-support-click.html is flaky due to "media.webkitPresentationMode" sometimes returning "inline" within a "webkitpresentationmodechanged" event handler after entering PiP. To reproduce, try to run this command:
Tools/Scripts/run-webkit-tests --release --time-out-ms=5000 --no-sample-on-timeout --exit-after-n-failures=1 --iterations=200 media/modern-media-controls/pip-support/pip-support-click.html
Adding a short timeout works around the problem:
media.addEventListener("webkitpresentationmodechanged", () => {
setTimeout(() => {
shouldBeEqualToString("media.webkitPresentationMode", "picture-in-picture");
container.remove();
media.remove();
finishJSTest();
}, 10);
});</pre>
