testcase

Currently, the preferredWidth is used for contentsWidth to compute children's position in render marquee,
but it is wrong when the children have a percent width type.

It was modified from overflowRect's width to preferredWidth by bug 64230,
but the preferredWidth is not same with the contentsWidth when the children have a percent width type.

So, overflowRect's width should be used for contentsWidth in here.
