Bug report: Tab window cannot be dragged back into window in vertical tabs mode

Description of the issue: After a tab has been pulled out of the vertical tab bar it cannot be dragged back into the tab bar of the other window.
How can this issue be reproduced?

  1. Right click tab and tick “Use vertical tabs”
  2. Open another tab and pull the tab out of the window
  3. Drag the tab in the new window and drop it on the vertical tab of the other window

Expected result: Selected tabs from the window merge into the window where it is dropped. (multiple tabs cannot be selected, see Bug report: Multiple tabs cannot be selected when using vertical tabs)

Actual result: The dragged tab becomes white and stays blank while being held over tab bar.
