------- Additional Comments from Beth Dakin <bdakin at apple.com>
In this patch I added comments to the files that render red to hopefully
provide some clarification whenever people come across these tests later.

I guess chromium bots are failing because they honor test results in the
platform/mac directory before looking at the test directory. Not sure what the
standard way to deal with that is.
