Description
What is the bug?
The LayerHitResult.coordinate seems to be in the wrong location (compared to the accurate MapOptions.onTap) when the map rotation is not 0.
Initially reported and initial MRE created at https://discord.com/channels/951867686378409984/1372837133546684437.
How can we reproduce it?

PolygonLayer(
