No response

Description

When using a parent scaled component and cdkDragFreeDragPosition with cdkDragScale, on first drag the element jumps and then the draging works correctly.

My guess is that passive transform in drag ref does not update to take scale into consideration

Reproduction

Steps to reproduce:

1. Add scale transform to parent component
2. Add cdkDrag, cdkDragFreeDragPosition (required) and cdkDragScale to draggable element

Expected Behavior

On drag when using scale, the element should not jump

Actual Behavior
