GeoJson Feature property with null value becomes "null" as string literal when querying rendered features

[codytodonnell]

This issue was originally raised and resolved in mapbox (see mapbox/mapbox-gl-js#8497) but is still an issue in maplibre.

maplibre-gl-js version: 1.15.3

browser: Google Chrome

Steps to Trigger Behavior

1. Set source data with a GeoJson FeatureCollection
2. The collection contains at least one feature with a property with a null value
3. When the feature is returned by map.queryRenderedFeatures(), the properties that originally had null values now have the literal "null" string as their value.

Expected Behavior

The value should remain as null.

Actual Behavior

The value became "null" as a literal string.

Can you check if this is still the case with the latest version?
Seems like this issue is with a dependency package and I believe the latest version has all the packages up-to-date.

No response, assuming this is fixed in latest version.
