Nit: m_element.currentTime() can be fairly expensive, so it would be good to cache it in a local instead of calling twice.

> Source/WebCore/html/MediaElementSession.cpp:995
> +    return NowPlayingInfo { m_element.mediaSessionTitle(), m_element.sourceApplicationIdentifier(), duration, currentTime, m_element.supportsSeeking(), m_element.mediaSessionUniqueIdentifier(), isPlaying, allowsNowPlayingControlsVisibility };

May as well also have a local for m_element.supportsSeeking() since it is used three times.

> Source/WebCore/platform/audio/cocoa/MediaSessionManagerCocoa.mm:242
> +    double rate =  nowPlayingInfo.isPlaying ? 1 : 0;

Nit: two spaces after '='

> Source/WebCore/platform/audio/cocoa/MediaSessionManagerCocoa.mm:276
> +    // FIXME: Fix this layering violation.
