Soul sand and magma block bubble columns don't move the player vertically in creative mode when not flying

The Bug

Bubble columns no longer push/pull the player in Creative mode. This occurs for both soul sand bubble columns and magma block bubble columns.

This was not the case in 1.21.1 (or 24w34a).

Steps to Reproduce

1. Dig a five-block deep hole in the ground and place soul sand or a magma block at the bottom.

2. Fill the entire hole with water so that they are all water source blocks. Note the bubbles appearing in the water.

3. Go into the water while in Creative mode.

Observed Results

The player does not get pushed/pulled by the water.

Expected Results

The player gets pushed/pulled by the water, like what occurs in Survival mode.
