Shadow Disappearance At Low View Angle

Another shadows issue.
Shadow objects are getting effectively culled when view angle is low and distance is substantial:

(The sphere is a unit)
I tried to show that when distance to object is small, it is not culled. However when distance is substantial, the problem starts to kick off.

No source files, tests, or entry points are identified. Start by reproducing the behavior shown in the linked video with a unit sphere, comparing a short distance with a substantial distance at a low view angle. Done means shadow objects remain visible at the substantial distance instead of being effectively culled.
