Player unable to move up water streams in certain directions while in lava

Description: There is a directional movement issue when attempting to step up from a lava source block onto an elevated water stream.

Setup / Scenario:

1. Place a 1-block lava source on the ground.

2. Place a solid block adjacent to the lava source, elevated by 1 block (1 block higher than the lava).

3. Place water on top of or flowing over this elevated block so that the end of the water stream flows toward the lava/player.

Observed Result: When the player is submerged in the lava source block and tries to walk up onto the elevated block with the water stream end:

• Moving North (-Z) or West (-X): The player can successfully step up onto the block.

• Moving South (+Z) or East (+X): The player gets stuck and cannot step up onto the elevated block at all.

Expected Result: The player's ability to step up onto the elevated water stream block should be consistent regardless of cardinal direction (North, South, East, or West).
