addSource geojson with "null" data renders previous geojson

[pomm0]

mapbox-gl-js version: 3.7.0

browser: Chrome for Linux: Version 129.0.6668.100 (Official Build) (64-bit)

Steps to Trigger Behavior

1. Add valid mapbox access token to jsfiddle
2. See the orange polygon which gets initialized with geojson data and is rendered properly. Script will remove and add the source + layer every couple of seconds with geojson data null:

Adding a empty featureCollection instead of null is behaving as expected:

map.addSource('my-source', {
   type: 'geojson',
   data: data ?? {
      type: 'FeatureCollection',
      features: []
   }
});

Should passing null as data work?

Expected Behavior

It renders nothing, since passed geojson data is null.

Actual Behavior

It renders previous existing geojson.
