 * all the translated strings, in a given locale for the specific file and
 * UIStrings object.
 *
 * Please note that this class is implemented with invariant in mind that the
 * DevTools locale never changes. Otherwise we would have to use a Map as
 * the cache. For performance reasons, we store the single possible map entry
 * as a property directly.
 *
 * The DevTools locale CANNOT be passed via the constructor. When instances
 * of `RegisteredFileStrings` are created, the DevTools locale has not yet
 * been determined.
