Describe the bug
I get an error when trying to test a component that contains a form with the @formname attribute
If I remove the @formname attribute, the error no longer occurs.
Here is a simple, reproducible repository
https://github.com/suzu2469/bunit-sample-tests

Example:
Testing this component: TestProduct.razor

<h1>Sample</h1>

<form method="post" @formname="sample-form">
	<button type="submit">Submit</button>
</form>

With this test:

@inherits TestContext

@code {
	[Fact]
	public void TestProductSampleTest() {
		var cut = RenderComponent<TestProduct>();

		Assert.NotNull(cut.Instance);
	}
}

Results in this output:

[xUnit.net 00:00:00.25]     SampleApp.TestProductTests.TestProductSampleTest [FAIL]
  失敗 SampleApp.TestProductTests.TestProductSampleTest [168 ms]
  エラー メッセージ:
   System.InvalidOperationException : Invalid element frame type 'NamedEvent'.
