Here, we have had an issue when switching from 5.11.1 to 5.15.2, with multi selection and dragNdrop Now, if we start a drag n drop, but previously clicked on the item a short time ago (less than the double click delay), then the view starts multi selection with the mouse moves instead of starting drag n drop, even if the mouse leaves the widget area. This did not happen in 5.11.1 with same user code, and dragging was enabled on a double-click+move I'm not sure which behaviour is better, but for our use cases, the former was more fitted.
Maybe looking at what changed between 5.11.1 and 5.15.2 (and why) could help your decision?
