[Bugs] Chat content cut-off on an ask_user interaction

**Mood:** 😔
**Category:** Bugs

Sometimes there is new content in the chat, and an interactive question that stops the flow and waits for the input. The bug is that the content before the question is not shown in full and can't be scrolled to the end. Sometimes it's misleading because there is no indication that some context is missing. Sometimes it's clear because the question is out of visible context, but there is no way to see it, except interrupting the question.

Comienza en la ruta /chat y reproduce una interacción ask_user después de añadir suficiente contenido como para requerir desplazamiento. Comprueba cómo la vista de chat gestiona el contenido anterior a la pregunta y, después, verifica que todo el contenido precedente sea visible y se pueda desplazar hasta el final mientras la interacción espera una entrada.
