Cloned items in JS-animated lists need live position mirroring

When mocking a new element into a live page with Playwright, cloning an existing <li> and appending it may not be enough if the site moves items with a scroll or rAF loop. The loop only updates the items it registered, so the clone keeps stale values and floats out of position; setting inline styles with !important does not address this. Let the page settle, read a registered sibling's current inline values (here --hang, translate, and the child's rotate), and copy them to the clone immediately before page.screenshot(), flipping the x sign if it sits on the opposite side of a symmetric curve. Inject your image as a base64 data URL so no local server is needed.
