[Task] Enable dragging elements with instant update

[atextor]

Is your task related to a problem? Please describe.
Dragging an element shows a dashed outline that I move instead of moving the actual element. This feels outdated. If it is for performance reasons, this should be configurable, like e.g. in Windows.

Describe the solution you'd like
Dragging an element does not show a dashed border but moves the actual element.

Describe alternatives you've considered
Make it configurable whether an outline or the actual element is moved.
