latency property
The MediaTrackSupportedConstraints dictionary's latency property
is a read-only Boolean value which is present (and set to true) in the
object returned by MediaDevices.getSupportedConstraints if and only if
the supports the latency constraint.
If the constraint isn't supported, it's not included in the list, so this
value will never be false.
You can access the supported constraints dictionary by calling
navigator.mediaDevices.getSupportedConstraints().
