What is the bug?

After Updating GDAL in my conda environment, reading administrative boundaries returns wrong results. Compare attached ogrinfo output from GDAL 3.12.1 vs. 3.10.3.

Steps to reproduce the issue

ogrinfo -q -ro -oo INTERLEAVED_READING=YES -sql "select osm_id, name, OGR_GEOM_AREA FROM multipolygons WHERE boundary = 'administrative' and name in ('Hessen', 'Kassel')" -geom=summary hessen-251219.osm.pbf
