I am trying to display rotated grid data from NetCDF in Leaflet.
When I try to use the "WMS angle parameter" (https://docs.geoserver.org/latest/en/user/services/wms/vendor.html#angle)
I got some strange results like this:

Any idea why this happens? I already have seen that there is the possibility to create a custom projection which allows to add rotation parameters, but I could not figure out how the correct usage is with using my own projection. Currently I am using (EPSG:25832) (Defining coordinate reference system with rotation in GeoServer?)
Would be nice to find a solution to display the rotation without manipulating the raw NetCDF data.
