Description Abrar Rahman Protyasha 2023-09-26 04:58:11 PDT

The `buttons` property on mouse events dispatched by WebAutomationSession is always zero, and does not correctly reflect what mouse button is pressed. I suspect the fix involves swizzling the `+[NSEvent pressedMouseButtons]` like in WKTR/DRT.

This will get us to fully pass the pointerevents/pointerevent_attributes_hoverable_pointers.html?mouse WPT.
