Disabling Cast Static Shadows on Stationary Lights causes dynamic shadows to not render

Regression: Tested in UE5/Release-5.1, this issue occurs as well.

The shadows render properly for the sphere when Virtual Shadow Maps is set as the Shadow Method, as well as when Ray Traced Shadows are used. When using Distance Field Shadows or Shadow Maps as the Shadow Method, the issue occurs.

1. Create a new Blank project
2. Set "Shadow Map Method" to "Shadow Maps" in Project Settings
3. Create a new Empty level
4. Create a cube and scale it to be a floor
5. Create a point light above the floor
6. Set the Point Light's mobility to Stationary
7. Create a sphere to cast shadows on the cube
8. Set the sphere's mobility to Movable
9. Set "Cast Static Shadow" in the Point Light to "False"

Actual Result: The sphere stops casting shadows on the cube.

Expected Result: Sphere continues casting dynamic shadows on the cube as you move it.
