A mousemove event is generated before mouseup when releasing mouse outside the "browser" window with sort-of-clipped coordinates, only on Webkit/GTK4, not with Webkit2/GTK3. Here's a test HTML file: <html> <head> <script> window.addEventListener("mousemove", function (ev) { document.body.innerText = ev.clientX + " " + ev.clientY; }); </script> </head> <body> </body> </html>
