MultiPolygon passes Polygon filter unexpectedly

[exe-dealer]

maplibre-gl-js version: 5.0.0

browser: firefox 135.0b1

Steps to Trigger Behavior

• create source with geojson multipolygon
• create fill layer with filter ['==', ['geometry-type'], 'Polygon']
• zoom map to layer

Expected Behavior

I expect MultiPolygon never or always pass filter ['==', ['geometry-type'], 'Polygon']

Actual Behavior

MultiPolygon feature passes filter somehow on random tiles and random zoom levels.

Is there any discussion about why geometry-type behavior was changed? Why do we need distinguish Polygon and MultiPolygon in styles?
