Reading Host Object Properties with parameters

Description
I have added a host object like this:

Public Class TestHost
	Public ReadOnly Property A(ByVal Name As String) As string
		Get
			Return "A"
		End Get
	End Property

	Default Public ReadOnly Property B(ByVal Name As String) As String
		Get
			Return "B"
		End Get
	End Property

	Public ReadOnly Property C
		Get
			Return "C"
		End Get
	End Property
End Class

The properties B and C are readable from scripting.
Reading property A throws an error:

Error: Falscher Parameter. (0x80070057)
    at RemoteMessenger.postSyncRequestMessage (<anonymous>:1:10501)
    at Function.getHostProperty (<anonymous>:1:22938)
    at Function._getAmbiguous (<anonymous>:1:13924)
    at Object.get (<anonymous>:1:15502)
    at WebView.js:14

Version
SDK: 1.0.864.35
Runtime: 91.0.864.54
Framework: WinForms
OS: Win10

Repro Steps
Add the the above host object.
Read A from scripting

console.log(window.chrome.webview.hostObjects.sync.TestHost.A("Z"))

I expect it to output the property value, but it throws the error.

Additional context
It looks like B is working because it is the "Default" property.
