Describe the issue
When using the command /speed only the fov changes in a weird way, let me explain: if you would do /speed 10 {playername} your fov would shrink dramatically and the playerspeed would not change as shown in this screenshot

When you write the command /speed 0.001 {playername} the same would occur, but now the fov is bigger as shown in the screenshot below

Crash/Error logs
No errors present

To Reproduce
Steps to reproduce the behavior:

1. Type in /speed 10 {playername} or any other speed value
2. Result is fov change but no speed change

Expected behavior
I expect it to change my players speed and fov correctly

@i509VCB Can you help me look into why walkSpeed and flySpeed abilities don't change speed?

[i509VCB]

I assume you are synchronizing the abilities on the server player after you set the value in the command?

[Martmists-GH]

Yup, otherwise FOV wouldn't change.

Cause seems to be that we need to use Entity Attribute Modifiers for changing player speed.
