Mouse hover on the at-panel disturbs keyboard select.
If the mouse remains at the 3rd item on the list,
when we press the up/down keys,
the list scrolls,
but the 3rd place would keep getting selected unexpectedly.
A workaround to avoid this if you care much about it,
is to disable the hover-selecting feature:
<at :hover-select="false"></at>
Fixing this bug with hover-select turned on (by default), is also under development.
