Steps to reproduce the problem:
1. Click on a nav button with a ripple effect

What is the expected behavior?
The ripple should fill the container

What went wrong?
On clicking a nav button (e.g. back) the ripple does not fill its container as the bookmark buttons do, but instead they morph into a circle shape.

A worse instance is clicking on the overflow menu (three dots) - the ripple will morph from a square, to a circle, and back to a square again. Apparently this pattern was created by the material team which is quite surprising, but one major difference at least is that the animation is eased (looks like ease-out-in). Currently it is a linear animation.

Did this work before? Yes

I think even to have the option of having regular input feedback instead like in MacOS would at least let users choose which animation style they prefer -- the code is already there for normal animations.
