Holding shift while descending not in hover mode slows descent but does not consume pressure

[Ace-Inventor]

What happened?

When ascending with hover mode on or off, hovering with hover mode on, or descending with hover mode on, pressure is consumed as expected. However, with hover mode off, it is possible to still press shift to slow your descent, and this does not consume pressure as expected. Additionally, no sounds are played and no particles are displayed. Expected behavior would be that pressure is consumed and sounds and particles are created as they are during normal ascent or hovering.

This can be easily replicated by equipping a filled jetpack, flying to a substantial height above the ground, disabling hover mode, holding shift, and observing that downward velocity stays at a constant low value similar to shifting while hovering, but no pressure is consumed as indicated by the pressure indicator remaining constant. See the video below, comparing the result of pressing shift with hover mode on, falling with hover mode off, and pressing shift with hover mode off.
