I have tested the fix. Forked in for my own use,

In my case, I had an with an empty Value (””) as my default item.

It works in the other cases. However, the defaullt value of Guid causes the field to not select the first item because it is not compatible.

My solution was to assign Guid.Empty as the Value for that firat item. Then it gets selected in a clean state.

I’m unsure whether it should treat Guid.Empty as ””, and vice versa.
