Accessibility: dragover fires immediately after dragstart in sortable

When dragging an item in a sortable, the initial announcements after starting a drag are:

from dragstart: Picked up draggable item {id}. from dragover: Draggable item {id} was moved over droppable target {id}. (i.e., itself)

In general, it makes sense for dragover fire consistently, but for accessibility, I can't think of a scenario where users would need the second message. If dragstart is defined, I'd expect the first dragover event after dragstart to be suppressed if the source and target id are the same.
