Steps to reproduce

After the “Windows 10 Anniversary Update” in EDGE browser I found a problem.
First. The “msRequestAnimationFrame” method is not always called a loop method.
Second. A “KeyUp” event is not always called after an “KeyDown” event.

  • run a project from attachment in EDGE browser
  • push a keyboard arrows

  • Also had this problem. A similar, perhaps related less common problem is that sometimes the keyDown event does not get called when the key is first pressed, only by the first auto-repeat. This problem can also be seen in the attachment here if you play around with it enough.
