genlist: fix item show/bring in coordinate calculation with zero-sized pan.

item show and bring can be processed with zero-sized pan.
item's coordinate will be calculated with this zero-sized pan,
so target position of scroll region bring in is not proper.

it occurs wrong result of SCROLLTO_MIDDLE and SCROLLTO_BOTTOM cases.

now we check pan size, and if less than 1, deferred call.

this is port of upstream patch D7037
