This issue has been fixed in Chrome canary(67.0.3379.0). Please note that, for the Chrome that doesn't have any profile shown up, user need to manually create one by clicking "Add Person".

This issue causing bad UX when both policies are enabled. I'd like to merge the patch into 66. The patch has also came with unit test.

This bug requires manual review: M66 has already been promoted to the beta branch, so this requires manual review
