SSAO Not Showing at Clipped Mesh Edges

## Bevy version and features

bevy = { version = "0.16.1", features = ["jpeg"] }

## What you did

Using StandardMaterial on everything in my game, I enabled SSAO with these settings:

Msaa::Off,
DepthPrepass,
NormalPrepass,
ScreenSpaceAmbientOcclusion {
quality_level: ScreenSpaceAmbientOcclusionQualityLevel::Ultra,
constant_object_thickness: 100000.0, // Maximum thickness for strongest effect
..default()
},
TemporalAntiAliasing::default(),

## What went wrong

SSAO works but doesn't show up where meshes clip each other. Mesh clipping isn't a bug in my game. I think it looks wrong to not have SSAO at the clipped edges, but I guess it might be hard to implement.
