Website: Patterns, Style, and Support not highlighting default page

[ArakTaiRoth]

Info

When you visit either the Patterns, Style, or Support links in the AppHeader, the default page for each is not highlighted in the Side Menu as being the active page.

This is also seen in this new PR for the new Foundations pages.

Acceptance Criteria:

1. Default pages when clicked in the AppHeader should indicate they are selected in the Side Menu

@ArakTaiRoth Might be fixed in #1973 , review after that is pushed
