Highlight Missing Shipping Method (PD-16429)

When a customer tries to click Submit Order without all info filled in, the page scrolls to top with a message in red saying fill in the missing stuff, and it highlights in red the missing field. That's great. Except when they neglect to select a shipping method, the red top message appears, but the shipping methods area doesn't get a red highlight.

Can the Shipping Method dropdown area highlight in the red when it's the missing information?
