Looks like you got a double changelong here.

Here too.

> +#if PLATFORM(MACCATALYST) || PLATFORM(MAC)

Could you add a ENABLE(MEDIA_USAGE) pragma and use it in platform-independent code instead? That way other ports could adopt without having to touch all these call sites.

> Source/WebKit/UIProcess/WebPageProxy.h:1739
> +    void addMediaUsageManagerSession(WebCore::MediaSessionIdentifier, const String& /* bundleIdentifier */, const URL& /* pageURL */);

Is there a reason these parameter names are commented out?

Fixed.

Good suggestion, changed.

Left over from an earlier version with more parameters. Removed.

Nit. Looks like these functions can be private?

document.fullscreenManager()...

R=me with just a couple of nits.

It's unfortunate you can't just re-use MediaUsageInfo here, and not re-declare the existing struct, but I guess that the URL -> DOMString for mediaURL makes that untenable.

Since structs have public members, there's no no need to prefix these with `m_`.

Do you want to include the exception.description here?
