[BUG] easing linear combined with tween not being linear.

[a-dominiak]

2. Describe the bug

When I use animate function to linearly transform motionValue from 0 to 1, It does not behave correctly. In the given link I attached a square that should just animate opacity from 0 to 1 and it starts at 0, but at about 50% it flickers.

3. IMPORTANT: Provide a CodeSandbox reproduction of the bug

4. Steps to reproduce

Steps to reproduce the behavior:

1. create a useMotionValue
2. create useEffect that changes that value
3. base some motion element style on it
4. It's not happening linearly

5. Expected behavior

The animation should be linear
