Subject: [PATCH] TASK: Add failing test for #5150, considering "Discard
 individual nodes"

Discarding individual nodes works through a separate command that still
needs to be considered by the recently introduced cache invalidation
mechanism in `WorkspaceProjectorCatchUpHookForCacheFlushing`.

This commit introduces a test that illustrates the issue.
