Allow UI context to update when selection is from 0

Previous condition was put in as part of I9ed6f9fb as a
temporary fix for bug 42842. However this code was causing
the popup widget to not appear for items at the start of
the document. It appears the bug it was put in to fix
has since been fixed elsewhere.
