envmapintensity does not work in latest threejs

[drcmda]

Description

envmapintensity does not seem to work in latest threejs, a material with roughness=0 and metalness=1 is always reflective, even with envMapIntensity=0. going back to three 162 the model becomes black immediately (which is correct).

For anyone also having problems with this update - here's more context: #27903

Since 0.163.0 material.envMapIntensity attenuates only material.envMap and the new property scene.environmentIntensity attenuates only scene.environment
