minecraft:movement no longer works correctly on the player

Gamemode One

Verification builds and Platforms:

v1.12.0, v1.13.0.1; Windows 10

Regression builds:

Correction: After further investigation, it turns out that v1.12.0 also has the bug in it. In fact, the component works perfectly fine if it's applied every tick (by a loop like the environment sensor) but not if it's only added once. That lead to an incorrect regression build on this report.

Summary:

minecraft:movement no longer works correctly on the player. Upon adding a component group with this component, the player does not receive the modified speed permanently. It seems like the speed gets modified for only a few ticks as the FOV changes for the split of a second.

Impact:

Affects upcoming content

Repro Steps:

• Download the attached BP and apply it to a world
• Join the world and type "/tag @s add show_bug"
• Observe the result

Observed Results:

The player's health permanently changes but the movement speed is not correctly increased.

Expected Results:

The new movement value gets applied correctly and therefor behaves like all other components.
