I've noticed that in editing mode the text areas allow to insert line breaks, for e.g. making a listing. But when back in displaying mode, all the entered text is displayed just in a single line.
(see attached screenshots).
Although the field is an textarea (regarding to the HTML-Code), there's no text editor added to this area just like it is with the text area at the description section.
I've also tried to insert tags like <br /> into the text, but it was just displayed as text and not interpreted as code (because in HTML-Code it is inserted as a string).
