If I open up a fresh browser instance and go directly to http://forum.somedomain.com/admin, any custom CSS settings specified in the Customize tab are not loaded.
That’s not a big deal, but navigating back to the forum home page (e.g. click on the “Forums” logo in the header) or to any topics seems to keep the non-customized layout. A full page refresh is required (on a non-admin page) to get the custom CSS to kick in.
Since the Admin pages already show custom CSS if visited after starting on the home page (or other non-admin pages), it would be nice if it was applied consistently.
