ComboBox demo does not work correctly

Hey guys,

I am trying to use a combobox for Vaadin 8 and noticed that after a new item is added, no other items are shown in a drop down list. It’s true for the demo code as well. If you will add a new country - nothing else is showing up.
Is there something missing in that code or it’s a bug?

Seems to me that this is another symptom of this issue

What do you think?

It sure is.
