Subject: [PATCH] Fixes visibility check using instance IDs

Ensures visibility checks within the filtering extension
correctly use instance IDs instead of raw object IDs.

This resolves issues where visibility states were not being
correctly applied to render view nodes, especially for instanced
geometry.
