Environment

Windows build number: 10.0.18363.836
WSL profile

Steps to reproduce

Use WSL profile, enable the mouse tracking mode SGR (1006):

echo -e '\e[?1003;1006h'

If you press the mouse button in the terminal window and move the cursor outside the window and release the button there, the application running in the terminal does not receive a message that the button has been released.

When the mouse tracking mode is on, while holding any mouse button and moving the cursor outside the window, the mouse tracking should not stop.

Expected behavior

If the mouse button was pressed inside the terminal, then the message about releasing the mouse button should come even if the mouse cursor has moved outside the window.

Actual behavior

А message about releasing the mouse button (and any tracking messages) does not come if the mouse cursor has moved outside the window.
