Due to 0a1a638553579d4effda75dc3c8f6e75aed97e15 (which was apparently intended to fix a FUOC), the styles are now loaded twice (once via the JavaScript ResourceLoader loader, and another time via addModuleStyles).
I think the correct solution is to make a separate module for styles that apply to HTML delivered from the server, and load that in the top queue. These styles should then be removed from the main module.
This top queue module could use addModuleStyles so at least the error text renders right if the browser doesn't have JavaScript.
