When creating a new translation, and the article title is removed, the input field gets a red border showing the magnifying glass icon misplaced. In addition to the icon position, the empty field should not be communicated as an error, the "start translation" button should remain disabled instead (while a valid article is not selected).
These observations may not be relevant if the new dialog for starting a translation is implemented, as proposed in T111094: Improve the New Translation dialog to easily find articles to translate
