Dnd drag cursor position (dragImage offset) is calculated incorrectly when using drag_handler

[vincentole]

Describe the bug
A clear and concise description of what the bug is.

To Reproduce
If possible please provide a StackBlitz based on this template
https://stackblitz.com/edit/ngx-drag-drop-issue-template-kgmw6q?file=src/app/app.component.html

Steps to reproduce the behavior:
2. Click on 'Handle'
3. Drag card down
4. See that the cursor position is not correct and the dragImage 'jumps'

Expected behavior
I would expect that the cursor would be exactly at the position on the drag handle when I drag the image.

The problem seems to be the default function for calculating the offset.
I tried to adjust the function, there always seems to be a glitch issue / bug so that the correct position could not be determined.
