commitWholePropertyOffset reduced the tween's keyframe list to find the "nearest" stop without an initial value. When a to()/from() tween had been collapsed to a zero-duration immediateRender hold (what removeAllKeyframes leaves behind), synthesizeFlatTweenKeyframes correctly treats it as a static hold and returns null, leaving an empty keyframe list — so the reduce threw "Reduce of empty array with no initial value". Reachable by resizing such an element with auto-keyframe recording off. With no keyframe shape to preserve, persist the flat value directly via an update-properties mutation instead.
