Hi @ScaryLarryGames1 , danke für den Hinweis.
Die Lösung war am Ende genau das, was du mit dem textarea vorgeschlagen hast, und wurde gerade gemerged. Gib es ein paar Minuten, damit es den CI/CD-Prozess durchläuft und in den latest-Branch kommt.

Follow up to #42192, which switched the composer field's hidden validation stand… -in from `type="hidden"` to `type="text"` so `required` would fire on submit. Text inputs strip CR/LF on value assignment per the HTML value-sanitization rules, and the reply body is assembled from these controls via `new FormData(form)`, so multi-line composer input came out flattened in the edit preview. Saved posts were unaffected because the raw source is read from the editor directly.
Swap the stand-in to a visually hidden `<textarea>`. Textareas participate in constraint validation just like text inputs, preserving the required-field enforcement from #42192, but do not sanitize newlines, so multi-line content survives in the preview.
