Chocobo1 10eb921d70 Allow drop action only on transfer list 
Now drop action is only allowed on transfer list, previously it was on main window.
Having drop action on the whole main window is not preferred because it could allow drop action
on other unrelated widgets, such as execution log or RSS widget which is unexpected behavior.

PR #21332.
