The dragged element must not overflow the parent container

When the dragged element is in a scrollable container, such as in a horizontal scrolling container, when the element is very long, the drag process will overflow the parent element, there is no way to solve this problem, very feel everyone's wisdom

Start by reproducing the drag in a horizontally scrollable parent with an element longer than the container, using the attached screenshot as the expected scenario. Trace the drag behavior that allows the element to overflow and determine how containment should work; done means the dragged element remains within its parent while scrolling and sorting still function.
