* ensures that only semantics boundaries will be added to owner._nodesNeedingSemantics as expected by compiler. * no longer throws assert if markNeedsSemanticsUpdate is called on non-semantic-boundary render object with a non-semantic-boundary parent. * Fixes #13109. * removes onlyLocalUpdates from markNeedsSemanticsUpdate as its no longer needed.
