Currently the PopupAutocomplete:

Always seem to set _popup.Visible = false; on Close.

In the TextField context, if the user is clearing current word this becomes an issue.

The RenderOverlay calls Close:

whenever the Suggestions.Count becomes 0, so when the user is clearing current word the _popup.Visible becomes false and nothing makes it true unless Reopen key is pressed.

Is this supposed to happen? Should we set the _popup.Visible = true whenever we try to render the suggestoins?
