Waterlogged blocks have no hitbox when eye level is in same block

When the player eye level is in a waterlogged block, its hitbox will be ignored as if the waterlogged block was not there. This affects all waterlogged blocks.

Note: repro steps simplified for clarity. The bug remains the same.

Steps to reproduce

1. Place a line of blocks, then one glass pane.

2. Waterlog the glass pane.

3. Stand with your eye level in the glass pane. Surround yourself with more glass panes so that you don't flow away. (see setup_82200.png)

4. /effect @p water_breathing 1000

5. /give @p netherite_shovel (or whatever tool breaks the line of blocks the fastest)

6. Attempt to break the waterlogged glass pane while facing the line of blocks.

In Survival mode, the blocks behind will be broken, while the glass pane remains untouched.

In Creative mode, the blocks behind will be broken first, followed by the glass pane itself.
