Components are resized by their parents, so even if an object is
updated/measured it will not be resized until the parent is updated. I'm not
sure what the timing of the parent updating is relative to adding a child.
After calling 'addChild()' and before calling 'layoutWindowsHorizontally()'
try explicitly calling 'child.validateSize(true)' and '
child.parent.validateDisplayList()'
