Sculk sensors are not activated upon flying in creative mode, whilst moving downwards and throwing a projectile at the same time

The Bug:

Sculk sensors are not activated upon flying in creative mode, whilst moving downwards and throwing a projectile at the same time.

Steps to Reproduce:

• Fly in creative mode without moving next to a sculk sensor and a shoot a projectile.
  →  Notice how the sculk sensor activates.
• Fly downwards in creative mode whilst next to a sculk sensor and shoot a projectile.
  →  Notice how the sculk sensor does not activate.

Additional Information:

Here's a quote from the 20w49a Changelog, which states that, "there are some motions that are undetectable to sensors by sneaking". Whilst the player is flying downwards in creative mode, they are not sneaking. They are instead moving downwards whilst flying, therefore a vibration should be emitted. I've attached a video which demonstrates this problem as this report may be quite difficult to understand.
