Mac control center "now playing" info not showing duration over 1h

Question

For a Mac app I'm trying to use the MPNowPlayingInfoCenter with playback controls and track info.

I'm using the MPMediaItemPropertyPlaybackDuration property to set the track duration, with the number of seconds as NSNumber wrapped value.

Tracks over 1 hour do not show the full duration and roll over at 59:59.

Is there any way to make items in the control center show their full duration & elapsed time?

Notes:

• The image shows Control center information for a track with a duration of 1:52:33 and current play position is 1:00:05.
• The seek bar works correctly.

That looks like a macOS bug since media played using QuickTime Player also exhibits the same erroneous behavior. Please file a macOS feedback report!
