Stop unexpected truncation of suggestion items.

The window's size is adjusted to be able to show all items in suggestion
popup window. So no need to specify ellipsize here.

Specifying ellipsize=marquee has a side effect that the 1st time of
width calculation may be different from 2nd or later time width
calculation since marquee may call compressText which request layout
asynchronously.
