Steps to reproduce

Please clone this GitHub repository MouseTests and run. Keep pressing the mouse inside the console and move around it, as the gif show.

Expected Behavior

The mouse events should be sent while the mouse button is pressed and moving inside or outside the console until it's released.

Actual Behavior

The mouse events are sent as expected except from outside of the console on top.

With the conhost the mouse events are always sent from anywhere while the mouse isn't released.

Yep, that's super weird alright!

Our theory is that we're getting into the mouse-select-drag-scroll state, and attempting to "scroll" the terminal, and suppressing the mouse event

Yep, I already noted that and that why I made my example writing always on the same line to avoiding scrolling. I noted that moving outside the console ws causing to scroll. This would be valid if I was pressed the scroll bar but that wasn't the case. Maybe acceptable only if the scroll bar is visible. Thanks.
