StocksApp hits an ASSERT when bringing up search

Previously we'd hit an ASSERT that elements in the style sharing list support
style sharing. However, it can happen that an element gets added to the style
sharing list and then loses the ability to share styles because it has an
active animation. This CL works around the problem by skiping over those
elements when considering style sharing candidates. A better solution would be
to clear the style sharing list when it might contain such an element. However,
it's likely we will remove style sharing in the future so its easier to just
work aroudn the issue for now.
