Describe the bug (required)

When a user drags a table row to the last position and then inserts a new table row, the new table row is inserted at incorrect position.

To Reproduce (required)

Steps to reproduce the behavior:

1. Drag and drop any table row to the last position (bottom-most)
2. Add new row (for example by arr.push)
3. Notice that element was inserted at incorrect position (the initial position of previously dragged row instead of at the last position)
