Editing commits made elements vanish or dim permanently: invalidating the whole timeline (or re-running the composition script on soft reload) made GSAP re-capture tween bounds while runtime transients were live — the grading hide's opacity 0, or a mid-flight tween value — so from()/to() bounds got poisoned and the element rendered invisible from then on. - patch only the edited tween in place, never timeline.invalidate() - soft reload restores every animated element's authored inline opacity (after-write HTML first, parse-time stamp as fallback) before the script re-runs and re-captures - a paired x/y commit whose second half is a no-op (changed=false) still applies its instant patch, so panel edits reflect without deselecting
