Comment 4 for bug 1671121

I explained 2) badly :) I was about to mean that use other component for delegate and put a button on it, so when you click it that button deletes the delegate. Just to rule out the ListItem itself. But the 1) already rules it out, so it is indeed the popover which does something bad. And probably it is related to the focus handling, as I do not see anything else the popover would affect the ListView functionalities.
