Description

If "focus follows mouse" is enabled, I expect that the window under the mouse is always in focus. But if the mouse changes windows during selection, the wrong (=focused window when selection starts) remains in focus.

To reproduce:

• Open two windows (e.g. xfce4-terminal, xterm, konsole) and place them side by side.
• Start selection in one window and move mouse during selection (=keep mouse button pressed) into the other window.
• Start typing --> wrong window

Expected behaviour: the window below the mouse gets focus when selection ends (mouse button is released).
