When flying at high speeds using Elytra, after landing, the walking effect is gone. The player will move normally without the walking effect.

Steps to reproduce:

1. Get a trident with high riptide level (1000 or over, so that you can reach speeds of more than 1 km/s, or 1000 blocks/s) and an Elytra, of course.
2.  Fly for a while and land (try going 100 - 200 km away from where you were). You will see you will be moving forward but in a static way, without the walking effect.
