Testcase

Steps to reproduce:
1) Open test case
2) Scroll up and down

Actual:
Top overscroll region is green.
Bottom overscroll region is red.

Expected:
Top overscroll region is red.
Bottom overscroll region is green.

The overscroll regions should look like extensions of the page. This bug breaks the illusion.
