The Bug:

Bubble columns retain their light levels from the sky after upgrading old worlds.

MC-258190 was partially fixed. While newly constructed bubble columns don't allow light from the sky to pass through them, old bubble columns that existed before upgrading worlds still retain their light levels from the sky.

Steps to Reproduce:

1. Launch an instance of 1.19.3 Pre-release 3 and create a new world.
2. Construct a bubble column in some deep water that has access to the sky.
3. Take note of how the light from the sky can pass through the bubble column.
4. Upgrade the world to a newer version of Minecraft and look at the bubble column.
5. Take note as to whether or not bubble columns retain their light levels from the sky after upgrading old worlds.

Observed Behavior:

Bubble columns retain their light levels from the sky.

Expected Behavior:

Bubble columns would not retain their light levels from the sky.
