WMS in EPSG:3857 discards geometry

Using http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/cultural/ne_10m_admin_1_states_provinces.zip for layer data.
Doing a WMS request in EPSG:3857 (Web Mercator) against this layer results in the vector geometry being truncated beyond the bounds of the projection. This results in malformed geometries - see attached examples.

This should throw an error rather than returning malformed geometry.

Nope, advanced projection handling should cut it properly, not throw an error. Unless you have it disabled, in that case there is no expected behavior, the code will just reproject point to point… from my tablet I cannot see the attachment, but want to make sure a regression is not put in code, throwing an exception that stops the rendering right away would be one unless endering is configured with a low error tolerance (hard to say what you mean exactly, not enough details)

Cheers
Andrea
