Hello!
I'm facing a problem when I try to render an accordion's panel when the first panel needs to be collapsed.

I found the collapsed tag helper and its description make me think it is the right one, but it doesn't work.

Look at this sample:

PanelCollapsed.cshtml
@page
@model ExtCookbook.Pages.PanelCollapsed
@{
}
<ext-section target="Main">
    <ext-container region="Center" scrollable="true" paddingAsString="30 20 30 50" layout="Accordion">
        <items>
            <ext-panel title="Collapsed" collapsed="true">
                <items>

                    <ext-button variant="Light"
                                scale="Medium"
                                marginAsString="5 0 0 0"
                                style="width: 100%"
                                text="hello"
                                hrefTarget=""
                                textAlign="Left"
                                iconAlign="Left"
                                cls="sidebar-nav-link"
                                iconCls="x-md save" />

                </items>
            </ext-panel>
            <ext-panel title="Expanded" collapsed="false">
                <items>

                    <ext-button variant="Light"
                                scale="Medium"
                                marginAsString="5 0 0 0"
                                style="width: 100%"
                                text="hello"
                                hrefTarget=""
                                textAlign="Left"
                                iconAlign="Left"
                                cls="sidebar-nav-link"
                                iconCls="x-md save" />

                </items>
            </ext-panel>
        </items>
    </ext-container>
</ext-section>
PanelCollapsed.cshtml.cs
using Microsoft.AspNetCore.Mvc.RazorPages;

namespace ExtCookbook.Pages
{
    public class PanelCollapsed : PageModel
    {
        public void OnGet()
        {
        }
    }
}
Is this the correct way?
Thank you
