The sidenav does not stay expanded on page refresh

[jerelmiller]

Description

When navigating the site, the sidenav expands/collapses the sections as you expect when visiting pages within a section. However, if you visit a page, then refresh, you'll notice the sidebar expands every section and does not highlight the current page you are on.

Steps to reproduce

1. Navigate to any page except the home page
2. Notice the side nav is collapsed/expanded propertly
3. Refresh the page
4. Notice that all sections have been expanded again and the current page is not properly bolded.

Expected behavior

Refreshing the page should not matter whether the sidenav is expanded or collapsed.

It looks like this might be a problem with the "server" generated markup. If I inspect the raw HTML downloaded for these pages, the HTML does not reflect the proper expanded/collapsed state.

This has been mostly resolved. Though I have noticed that upon refresh you see the expanded nav blink before showing the correct collapsed/expanded state
