If any of the styles given in its module definition (in the 'styles' or 'skinStyles' properties) used the same media queries as the module's own CSS (e.g. 'all'), the module would fail with "PHP Fatal error: [] operator not supported for strings" because FileModule defaults to merging all the stylesheets into a single string. Fix this by ensuring they are arrays before trying to extend them. This previously made it impossible to use $wgResourceModuleSkinStyles for modules that use SkinModule (instead of plain FileModule), such as the 'mediawiki.skinning.interface' module.
