tvOS14, custom playback events aren't visible in javascript environment

Hi, after update to tvOS14 I noticed that custom events that are dispatched by TVPlayer instance are not visible from JavaScript environment. Before update to tvOS14 everything worked fine. Something was changed in meantime?

Did anyone observe that behaviour too?

Code Block 
tvplayer.dispatch(event: TVPlaybackEvent(rawValue: "customEvent"), userInfo: properties) { (feedback) in
	.....
}

and in TypeScript we register simple event listener:

Code Block 
player.addEventListener("customEvent", async event => {
...
}
