Razor intellisense not working with tag helpers using ParentTag

[jamezamm]

Hi,

I am using Visual Studio Enterprise 2022 (x64) Version 17.6.6.

I have the below tag helper classes:

/// <summary>
/// This is a container
/// </summary>
[HtmlTargetElement("container")]
public class ContainerTagHelper : TagHelper
{
	public override void Process(TagHelperContext context, TagHelperOutput output)
	{
	}
}

/// <summary>
/// This is a header
/// </summary>
[HtmlTargetElement("header", ParentTag = "container")]
public class ContainerHeaderTagHelper : TagHelper
{
	public override void Process(TagHelperContext context, TagHelperOutput output)
	{
	}
}

The razor page syntax:

<container>
	<header></header>
</container>

For the container tag, intellisense works as expected. Meanwhile for the header tag, intellisense does not popup when hovering the mouse over the tag.

Removing the ParentTag solves the issue.

Surprisingly, completion actually worked fine :)

The above issue has been fixed. But another small issue remain.

Continuing on the above example:

Tag Helper Class:

/// <summary>
/// This is a header
/// </summary>
[HtmlTargetElement("header", ParentTag = "container")]
public class ContainerHeaderTagHelper : TagHelper
{
        /// <summary>
        /// This is a test property
        /// </summary>
        public string Attribute { get; set; }

	public override void Process(TagHelperContext context, TagHelperOutput output)
	{
	}
}

Razor Page Syntax:

<container>
	<header attribute='test'></header>
</container>

Summary for property Attribute does not show when hovering the mouse over the attribute in razor syntax.
