Short description of error
When using Instancer/Object type Attribute node in material with Displacement/Vector Displacement in EEVEE-Next shading has artifacts and no displacement.

Exact steps for others to reproduce the error
Prerequisites:

Object is instantiated via GN (or instancing).
Object has material with displacement (or vector displacement) and material displacement method is set to Displacement and Bump.
EEVEE-Next is used as render engine.
Viewport shading is set to Rendered.

Steps:

Add Attribute node to material
Set attribute type to Instancer (or Object)
Link Attribute node to Material Output node (or other shader tree node)

Expected result: Object is displaced and shaded properly.

Actual result: Object has shading artifacts with no displacement.
