This test verifies that stacking contexts are correctly created and removed when CSS properties that affect stacking context are changed: - opacity: transitioning to/from 1 - transform: transitioning to/from none - filter: transitioning to/from none - isolation: transitioning to/from isolate It also verifies that changes within the "creating" range (e.g., opacity 0.5 -> 0.3, or transform translateX(10px) -> translateX(20px)) correctly preserve the stacking context.
