limit on .api.library.playlists()?

Been playing around trying to pull my cloud playlists using musickit.js however it seems there's a max limit of 100? How do I change that?

let apple_player = MusicKit.getInstance();

var params = { limit: 2000 }

let apple_playlists = apple_player.api.library.playlists(params).then ( function( playlists ) {

// user's cloudPlaylists

alert ( playlists.length);

console.log( JSON.stringify(playlists) );

});

this only returns 100.
