Not smooth when dragging in list

I have a problem that when I drag an element, I find that it does not animate smoothly and appropriately, and I feel that there may be a problem with the recognition of the corresponding height

I want to know why and how to fix it, thx~


Start by reproducing the drag interaction shown in the attached GIF using the repository's sortable list components. Trace how the dragged element's height is recognized and how list animation is triggered; done means the affected list drags smoothly and the behavior is covered by a reproducible verification.
