FLEX-35321 CAUSE: If a component is removed from stage during a validation cycle, the LayoutManager nevertheless sets its initialized flag to true, even if it's not on stage anymore. That's because it doesn't check at the end whether the component is still on stage.

SOLUTION: Now the LayoutManager verifies that the component is still on stage before initializing it.
