Shapes: Wiggle Paths has Spatial Phase, which slides its wiggle along the path

Shapes: Wiggle Paths has Spatial Phase, which slides its wiggle along the path ## What Wiggle Paths had no Spatial Phase. After Effects lists Spatial Phase (`ADBE Vector Spatial Phase`) among the Wiggle Paths properties in the [scripting match names](http://web.archive.org/web/20260603134235/https://ae-scripting.docsforadobe.dev/matchnames/layer/shapelayer/), and [Shape attributes, paint operations, and path operations for shape layers](http://web.archive.org/web/20251209024058/https://helpx.adobe.com/after-effects/using/shape-attributes-paint-operations-path.html) ("Wiggle Paths") says several of its properties "behave the same as properties of the same name for the Wi
