Safari movemove event is not fired when mouse is over disabled element (whereas it is triggered in Firefox and Chrome)

In a web extension, I am trying to highlight and capture the element over which the mouse is currently hovering.

However, the mousemove event does not trigger in Safari when the mouse is over a disabled element.

This code will print the mousemove event details in Firefox and Chrome, but print nothing in Safari:

Code Block javascript
document.addEventListener("mousemove", (event) => console.log(event));

I've also tried putting the event listener on window instead with the same result :(
