Removing Mesh3d but keeping MeshMaterial3d stops material from rendering for all entities using it.

Bevy version 0.16.0

System information

```ignore
AdapterInfo { name: "AMD Radeon Graphics (RADV RENOIR)", vendor: 4098, device: 5708, device_type: IntegratedGpu, driver: "radv", driver_info: "Mesa 25.1.4", backend: Vulkan }
```

## Step to reproduce

Use a same material for different entities with `Mesh3d`. Then remove the `Mesh3d` component from one of them.

```rust
#[derive(Component)]
struct Marked;

commands.spawn((
Transform::default(),
Mesh3d(sphere.clone()),
MeshMaterial3d(material.clone()),
));
commands.spawn((
Marked,
Transform::default(),
Mesh3d(sphere.clone()),
MeshMaterial3d(material.clone()),
));
```

```rust
fn delete_mesh3d(mut commands: Commands, marked: Single>) {
commands.entity(*marked).remove::();
}
```

## Expected behavior

The entity whose `Mesh3d` was removed, no longer renders. All the others still do and no warning is raised.

## Actual behavior

Most entities sharing the same material as the entity whose `Mesh3d` was removed, stop being rendered. No warning nor error is reported. Not all entities are affected and the behavior seems to not be deterministic.
