[MC-63021] Some chunks in view of the player are not rendered in certain circumstances (incorrect occlusion culling)

The bug

Sometimes, chunks in view of the player don't render because the game incorrectly determines that the chunk is hidden behind an obstruction.

This issue is actually a separate issue to that of MC-63020 (which describes an issue regarding frustum culling).

I've re-opened this issue as the original frustum culling bug described by MC-63020 is resolved. This issue should now be used for tracking the bug related to "occlusion culling", which is not fixed.

For reference, the occlusion culling bug is identified by having a chunk disappear directly in-front of the player (not in the very edge of the screen) and re-appears when the player moves into the area of the missing chunk - or when the player destroys a block somewhere around the chunk's boundary.

Resolved in favor of MC-70850 since it contains more information and has been open for longer.
