Broken SVG display

The `@@iconresolver` view removes the `id` attribute from `<svg>` tags, but this attribute is needed for displaying repeatable elements with `<use>` ('href' and (deprecated) 'xlink:href').

The error is visible, when you're activating the brazilian flag in the language selector.
