+; Normally, themes may list CSS files like this, and if they exist in the theme
+; folder, then they get added to the page. If they have the same file name as a
+; module CSS file, then the theme's version overrides the module's version, so
+; that the module's version is not added to the page. Additionally, a theme may
+; have an entry like this one, without having the corresponding CSS file in the
+; theme's folder, and in this case, it just stops the module's version from
+; being loaded, and does not replace it with an alternate version. We have this
+; here in order for a test to ensure that this correctly prevents the module
+; version from being loaded, and that errors aren't caused by the lack of this
+; file within the theme folder.
