TextView doesn't work in ListView

[WhiteBlackGoose]

It just doesn't display and I can't find any way to make it. I bind its buffer's property to the property I need, and if the text view is placed elsewhere it works, but if it's inside an entry of a list view, it just doesn't display anything and doesn't resize.

To repro:

1. Take the todo app
2. Replace Label with TextView and the property binding as follows:

        let content_label_binding = task_object
-            .bind_property("content", &content_label, "label")
+            .bind_property("content", &content_label.buffer(), "text")
            .sync_create()
            .build();

3. Now it's just empty stuff in the app

If needed, I'll prepare a single file repro without building on top of that todo example

It shows up if you set hexpand to true on the GtkTextView.
