Sidebar order only loads when on main overview when installed through HACS

[Timmiej93]

When I do a hard refresh (CTRL+SHIFT+F5) of any page in the sidebar other than the main overview page, or go there through a direct link, the custom sidebar order doesn't load. This is with custom sidebar installed through HACS, and browser mod installed as well. When I add the frontend section to my config file, the sidebar order does load properly, immediately, regardless of which page I'm opening. Sadly though, this results in all items that are new_item's to appear twice in the sidebar. However, that only happens when going through a proxy, i.e. homeassistant.mywebsite.com. It doesn't happen on mylocalip:8123. It's not a massive problem, but it is quite annoying. Issue #35 has roughly the same thing going on with the doubling up of the new_item items.
