createTimelineElementFromManifestClip used `clip.zIndex ?? computed`, but the runtime reports inline-only z-index (0 for CSS-rule authored z-index), and `0 ?? x` keeps the 0 — so every CSS-styled clip collapsed to a z=0 tie. The timeline then ordered rows by DOM position instead of true stacking, and the first vertical drag renumbered the whole tie group, clobbering the author's z-index. Prefer the effective computed read from the live element (the same read the reorder commit uses); fall back to the runtime value only when the element isn't live.
