Steps to reproduce the problem:
1. Set Shelf mode to "Autohide Shelf"
2. Mouse over shelf
3. Shelf shows rounded corners, straight corners, rounded with an additional rounded or straight outline, or some combination thereof. 

What is the expected behavior?
Shelf should pop up with either rounded or straight corners (I don't know which is intended), not a mixture.

What went wrong?
The shelf appeared in a few different shapes:
1) Rounded corners, but a light gray straight bar appeared on the left
2) Slightly rounded corners on both sides (maybe correct?)
3) The left corner is straight, the right corner is rounded
4) Both corners are rounded. The left corner displays a rounded bar with a different curvature than the shaded part of the shelf. The right corner has a straight bar.
5) Both corners are straight.
6) The left corner is straight, the right corner is more rounded than #3.

Did this work before? Yes The last version of Chrome OS

Chrome version: 70.0.3538.76  Channel: stable
OS Version: 11021.56.0
Flash Version: 31.0.0.122 

It's a visual bug and doesn't really effect behavior, but is distracting and confusing. The bar should not be a strange mixture of different curves and straight lines.
