Description
Th ExtendedFloatingActionButton does't shrink when it's a child of a Motionlayout. I think because it update its size in the with:
`layoutParams.width = size.getWidth()`
`layoutParams.height = size.getHeight()`
(in ` ChangeSizeStrategy.performNow() `)
which shouldn't be done like that when the `layoutParams` is a `ConstraintLayout.LayoutParams`.
