Steps to reproduce

Create an HTML page containing a DIV element.
Attach an eventListener to the DIV element observing the mousemove event and have the callback log something in the console.
Move the mouse pointer over the DIV element and press and hold the left mousebutton.
Observe that after holding the mouse button for about 1.5 seconds a log message appears in the console, showing that a mousemove event was registered by the eventListener.

I would expect no mousemove event to be triggered by pressing and holding a mousebutton while not moving the mouse.
