The movement_speed attribute has no effect on flying mobs

The bug

Mobs which fly (ghasts, bats, vexes, etc.) are not affected by the movement_speed attribute as terrestrial mobs are.

How to reproduce

Run the following:

/summon bat ~ ~ ~ {attributes:[{id:"minecraft:movement_speed",base:0d}]}

Observe how the bat flies around at normal speed.
