R=me with just a couple nits:

> Source/WebKit/UIProcess/API/Cocoa/WKWebView.h:351
> + WKNoMediaPlayback and the callback will return the error
WKErrorNoMediaPlayback.

This makes it sounds like an error will be returned if there’s no media
playback.

> Source/WebKit/UIProcess/API/Cocoa/WKWebView.mm:931
> +    return _page->requestMediaPlaybackState([completionHandler =
makeBlockPtr(completionHandler)] (auto&& mediaPlaybackState) {

I think this needs a nil check on completionHandler.
