Draggable Dialog position jumps when scrolled down page

Question

When using a modal dialog that is configured to be draggable, the position of the dialog will jump down when clicking on the dialog to drag it if the page is not scrolled to the very top. the amount the dialog jumps appears to increase the further scrolled down the page you are.This is using the current latest version of syncfusion, V18.3.0.40. This has been replicated in the latest versions of both Chrome and Firefox on a Windows 10 machine.

Please see below demo and attached solution demonstrating the issue.
