Panzoom not working with draggable

[grayter1]

Hi, i have an issue with using panzoom/draggable together. I ask question on SO here: https://stackoverflow.com/questions/61497990/unexpected-behavior-of-svg-draggable-panzoom, and here is the jsfiddle: https://jsfiddle.net/grayter/uhde3ykw/29/

The problem is in dragging group - content of group is flowing. Is there some way to fix it? I need this very much to my project. Help will be appreciated.
