Blazor components do not work in partial views.

[wocar]

Describe the bug

Blazor components do not work in partial views.

To Reproduce

I have Index.cshtml that Invokes a partial view called _details.cshtml
Within that partial view I'm trying to invoke Details.razon Razor component like this:

@(await Html.RenderComponentAsync<Details>(RenderMode.ServerPrerendered))

Events don't get fired but content does get rendered.
If I use

@(await Html.RenderComponentAsync<Details>(RenderMode.Server))

The content doesn't even get rendered. On the other side, if I use either of the above in the Index.cshtml the component works perfectly.

Here is the Details component code

@using System.Net.Http
@using Microsoft.AspNetCore.Authorization
@using Microsoft.AspNetCore.Components.Authorization
@using Microsoft.AspNetCore.Components.Forms
@using Microsoft.AspNetCore.Components.Routing
@using Microsoft.AspNetCore.Components.Web
@using Microsoft.JSInterop

<h3>Event Binding</h3> <br /> <br />
<button @onclick=@ButtonClicked>Event Binding Example</button>  <br /> <br />
<button @onclick=@(() => Message = "Inline:Button Clicked")>Inline Event Binding</button> <br /> <br />
<p>Message: @Message</p>

@functions {
    private string Message { get; set; } = "";
    void ButtonClicked()
    {
        Message = "Button Clicked";
    }
}

Any clues? Is this scenario supported? Thank you.
