Transform is not updated on scroll

Enabling scrolling on the example for the https://kizu.dev/position-driven-styles/#distributing-anything-property, then selecting an item and scrolling the container results in the element's transform change not being reflected on the minimap.

Reproduce the problem using the linked position-driven styles example: enable scrolling, select an item, and scroll its container while watching the minimap. No files or tests are named, so first locate the code that updates the selected element's transform and minimap, then add coverage for the transform changing during scroll. Done means the minimap reflects the element's current transform.
