In Firefox debug builds, there is an assertion to check that we don't connect a subelement of an already connected root. Thanks to this assertion, we can see that the root has already been added to Fluent, hence we don't need to do it a second time.
We don't need to await anymore on the translation in order to update the toolbar: it'll be done by Fluent, so we can safely remove the "localized" event and avoid to wait for it.
