Unblocked point lights farther than 3 blocks from a surface cast broken shadows

Steps to Reproduce:

1. Import any resource pack with PBR capabilities;
2. Enable the experimental toggle for Render Dragon features;
3. Switch rendering mode to "Deferred Technical Preview";
4. Set Shadow Quality to Medium or higher so point light shadows are enabled;
5. Try either of the following scenarios:

• Place a block at least 4 blocks off the ground, then place a torch on one of its sides.
• Place a block with a shadow smaller than a full block at least 3 blocks off the ground, then place a torch on top of it.

Observed Results:
The light that hits the ground has a circular shape with hard edges and a larger square shadow around it.

Expected Results:
The light and shadow behave the same regardless of the distance between the source and surfaces.
