Summary Legacy scrollbar corner pseudo styles used despite standard scrollbar properties

`scrollbar-color` and `scrollbar-width` disable `::-webkit-scrollbar` styles when set to non auto values. But they don't disable `::-webkit-scrollbar-corner` styles. This bug will address that and add necessary tests.

Some of the tests added here fail on Firefox because of the non-standard `::-webkit-scrollbar-corner`. Can you please move those tests somewhere else? Thanks!

It's not because of the non-standard property. I was careful to only write tests that negate that property so it will work in Firefox. The issue is because I messed up the refs and they don't have scrollbar-color declarations. Will fix now.
