-// MediaControlsOrientationLockDelegate is implementing the orientation lock |
-// feature when a <video> is fullscreen. It is meant to be created by |
-// `MediaControls` when the feature applies. Once created, it will use events to |
-// change state. |
-// |
-// The different states of the class are: |
-// - PendingFullscreen: the object is created and is waiting for the associated |
-// <video> to go fullscreen in order to apply an orientation lock; |
-// - PendingMetadata: the <video> is fullscreen but the metadata have not been |
-// downloaded yet. It can happen because of network latency or because the |
-// <video> went fullscreen before playback and download started; |
-// - MaybeLockedFullscreen: the <video> is fullscreen and a screen orientation |
-// lock was applied. |
-// |
-// The possible state transitions are: |
-// - PendingFullscreen => PendingMetadata: on fullscreenchange event (entering |
-// fullscreen) when metadata are not available; |
-// - PendingFullscreen => MaybeLockedFullscreen: on fullscreenchange event |
-// (entering fullscreen) when metadata are available; |
-// - PendingMetadata => MaybeLockedFullscreen: on loadedmetadata; |
-// - PendingMetadata => PendingFullscreen: on fullscreenchange event (leaving |
-// fullscreen); |
-// - MaybeLockedFullscreen => PendingFullscreen: on fullscreenchange event |
-// (leaving fullscreen). |
