Attribute generic.movement_speed does not work in /attribute

If you change your generic.movement_speed attribute at all, it instantly reverts back to its original value of 0.10000000149011612. There is no way to make it stay at the value you wish to set it to.

How to reproduce

1. Use the attribute command to give yourself a higher movement speed

   /attribute @s minecraft:generic.movement_speed base set 50

   Your movement speed is reverted back to the default speed
