Steps to reproduce issue:

1. Navigate to Control Panel > Sites > Sites
2. Add a new site
   • Enter a name for the site
   • Press "Save" button

Expected result: Product Menu and portlet header remain intact.
Actual result: Saving the new site causes the portlet header and Product Menu to lose their styling. Refreshing the page does not return the styling to the portlets.
