Drag and Drop of text/link is not working for the last two tabs in Vertical tabs

[jagadeshjai]

Description

• Drag-and-drop of text or links does not work for the last two tabs when vertical tabs are full or overflowing.
• It works fine for the last two tabs when vertical tabs are not full. Essentially, the end of the vertical tabs (last two tabs before new tab button) is not being recognized as a valid drop location.
