Weird selection behavior with combobox and gridview using MVUX

[modula2019]

Hi all,
I again notice something weird with this combobox and the gridview. I don't know if it is a bug with selection.

Using the combobox, I notice that the selection only gets triggered on the 1st or 2nd attempt. Subsequent selection triggers do not work.
Using the combobox, I also notice that when you set the initial data in the combobox to the below, the selection trigger does not work.
public IState<Person> SelectedPerson => State.Value(this, () => new Person(FirstName: "Master", LastName: "Yoda"));

If you do the same for the GridView and you attemt to select the next record, there is an error (This collection cannot work with indices larger than Int32.MaxValue).

It seems the selection only wants the initial record to be empty like below. Empty record works perfectly for the GridView but not for the ComboBox.

`public IState<Person> SelectedPerson => State<Person>.Empty(this); `

But this is not always the case because I may want to default my initial selection to a particular record number (index) in the list.

I also notice when I make changes to the xaml and save, the Hotreload does not work anymore. I am on VS 17.9.6

Thanks for your assistance as usual.
