Error, when closing tabs too fast : "List index out of bounds (-1)"

System: Window 10
Transfer Protocl: SFTP
Reproduction steps:

  2. In the Login dialogue create a new folder (not sure if this is needed).
  3. Save 7 SFTP sessions to similar IPv4-Adresses in that folder, with password stored.
  4. Right click the new folder and select open, to open the 7 tabs for the 7 sessions.
  5. Click at each tab and let WinSCP connect to the server and display the folder.
  6. Hover with the mouse over the close-button (x) of the left-most tab. Now left-click very fast at least 7 time at the close-button.
  7. Error window appears: "List index out of bounds (-1)", Content:
