Misleading initial language selection in TranslationWizard
copied from #8147:
When opening the translation editor the first language in the list of available languages is shown in the right dropdown. But the data for this language is not loaded into the form.
We either need to show no text in the language dropdown to make clear no language is chosen yet or we should load the form with the data for the shown language.
This might be another ticket so feel free to close this and open new one.
