CDK Drag boundary is not working for SVG element

I am working on one project which having functionality to draw shape and drag it in it's container but when I used cdkBoundary for rect element and drag it then transform property updated base on top most parent's coordinate.

Start with the Angular CDK drag-boundary behavior for an SVG rect and reproduce the case described in the issue, focusing on how the transform is calculated relative to the topmost parent. Confirm the boundary keeps the SVG element within its container while preserving the expected coordinate system.
