WindowsDriver is sending mouse button pressed only on moving.

          Open `Buttons` scenario and move the mouse around the window without pressing. The screen will be all black. Pressing Esc it's possible to exit.

You can check it in action by opening the Mouse scenario.

I think this issue is related with how Windows Terminal handles the mouse with app that are using the Win32 API to handle the mouse. Using the conhost this issue doesn't reproduces. @tig can you please ask to them about this. Thanks.

Using the Command Prompt on the Windows Terminal doesn't also have this issue.
Another issue which I'm facing lately is when I move the Windows Terminal from one monitor to another where the screen is badly rendered. This happens with all consoles on the Windows Terminal.

This is still happening even after the PR #3382, not so often but sometimes. To ensure it will emit Button1Pressed double click on the Mouse scenario and move quickly the mouse outside the terminal and then move again into the terminal and normally we'll see Button1Pressed, ReportMousePosition
