ball with PhysicsMaterial2D.bounciness = 1 bounces higher with each bounce
Steps to reproduce:
1. Open attached project "bouncetest.zip"
2. Open "bounce_scene" scene
3. Run the scene
4. Notice how "ball" bounces higher with each bounce even though bounciness is set to 1 (Editor outputs max height in Console, .gif attached)
Expected behavior: according to documentation("The degree to which collisions rebound from the surface. A value of 0 indicates no bounce while a value of 1 indicates a perfect bounce with no loss of energy.") the ball should bounce perfectly and reach the same height with each bounce.
Reproduced with: 5.2.4f1, 5.3.5p5, 5.4.0b24

I had the same issue in my own project in 5.6.1f1.
Setting the collision detection on the ball to "Continuous" resolved the issue.

So while a value of 1 indicates a "perfect bounce with no loss of energy" according to the documentation but the ball actually loses energy and slows down, how is this behavior "by design"? This needs an explanation.
So how do you get a ball to bounce without losing energy then?
