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
Use the
attributecommand 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

Is this similar to how potion effects change back to the normal value when the multiplier is too high?
I can confirm it still exists 20w22a.
A good workaround for now is using a modifier instead of setting the base. Modifiers seem to work for generic.movement_speed.

I have noticed this too.
