I think the `testAnchorRight` is failing because the change exposed a bug somewhere else. The problem seems to be on the `topLeft.getBoundsInParent().getMinX()` function that returned `556`  before and is returning `554.5999755859375` now. So `requestFocus` causes some recalculation that is probably wrong.
