Description

Context According to the official documentation, the property "pointerPosition" of the "CdkDragMove" event is : "Position of the user's pointer on the page." See : https://material.angular.io/cdk/drag-drop/api#CdkDragMove

Problem If I use the "cdkDragBoundary" property, the property "pointerPosition" returns cursor position only between boundaries.

Reproduction

StackBlitz link: https://stackblitz.com/edit/stackblitz-starters-knrvcz?file=src%2Fmain.ts Steps to reproduce:

1. Move the red block until the cursor moves out of the blue block
2. At the bottom of the blue box, you will see that the cursor position is stuck to the boundaries of the blue box.

Expected Behavior

I expect to have the current position of the cursor on screen, wherever it is located.

Actual Behavior

The position displayed of the cursor is limited to the limits of the blue block
