When a container's child count goes to zero, it may report a measurement size of zero. This affects LayoutTransition's fading-out of target views because they may get clipped out by a layout that got sized to 0 because it thinks it has no children. The workaround is to tell the layout to size itself either with some minimal size (in the case of the FixedGridLayout used by some demos) or with match_parent in some cases to ensure that the layout always has some nonzero size.

Adding a new folder in development/samples is not enough to have it be packaged with the SDK. Make sure to edit development/build/sdk.atree to add the sample to the SDK build.
