Note that we will now fail if `inlineImports` is enabled and we cannot resolve an import. You can work around this by either: * Use url imports or imports with media queries. * Set `skipInlineImportsNotFound=true` in the options Also get the argument order in the different NewFileError* funcs in line. Fixes #9895
