Found this bug as a result of improving our constraints logging in bug 1494498.

STR:
 1. Open https://jsfiddle.net/jib1/4wp15e6u/ which does this:

    await navigator.mediaDevices.getUserMedia({video: {deviceId: {exact: ["boo"]}}});

Expected result:
  OverconstrainedError

Actual result:
  Succeeds in spite of unknown deviceId.

Workaround:
  Avoid arrays:
    await navigator.mediaDevices.getUserMedia({video: {deviceId: {exact: "boo"}}});
