Elytra climbs infinitely and speeds up holding jump button Creative mode (Nintendo Switch)

Steps to reproduce

1. Launch Minecraft on Nintendo Switch

2. Load a Creative-mode world

3. Put on elytra as chest armor

4. Jump from high ground to enter elytra gliding state

5. Hold down the jump button continuously while gliding

   Expected result

   When gliding with elytra in Creative mode, holding the jump button should not let the player gain vertical altitude. Infinite upward acceleration should not occur.

   Actual result

   Without using any firework rocket fuel, the player keeps climbing higher. The flying speed becomes faster and faster as you keep holding jump. This bug occurs on nearly all Switch versions.
