Update ScrolledWindow height in Popover

Platform
1

I spent few days but still can’t find solution to update ScrolledWindow height after update its child (by model factory)

I have following configuration:

Popover::builder()
    .halign(Align::Start)
    .child(
        &gtk::ScrolledWindow::builder()
            .child(&list_view)
            .max_content_height(400)
            .hscrollbar_policy(gtk::PolicyType::Never)
            .propagate_natural_height(true)
            .propagate_natural_width(true)
            .build(),
    )
    // ..

The window size is always fixed after init, and always same to initial child height. Already tried queue_resize and set_height_request on childs update but no success.

In other words, when the child in ScrolledWindow reduces its height, the ScrolledWindow keeping same:

I just forgot to change valign property to GTK_ALIGN_START for the Popover (it was GTK_ALIGN_FILL by default)
