Issue
When a table has collapsible items, or the table row has dynamic items depending on vue directive v-if/v-show,
the dragging behavior is wired and the sorting order is wrong.
Root Cause
In addition to the actual rows, the rows with v-if directive false will be comment nodes which causes the dragging target is wrong.
Solution
Filter out comment nodes to avoid the bug
