Weird behavior of long presses in Chrome and Firef

问题:

So, I found some weird behavior of long presses in Chrome and Firefox for Android. I'm trying to avoid scrolling, context menus, vibration and selecting text. Also, I need the touch not to be canceled. I set a simple page like this:

var logger = document.getElementById("logger")

function touchHandler(e) {
  e.preventDefault()
  logger.innerText += e.type + "\n"
}
function contextMenuHandler(e) {
  e.preventDefault()
  logger.innerText += e.type + "\n"
}

window.addEventListener("touchstart", touchHandler)
window.addEventListener("touchmove", touchHandler)
window.addEventListener("touchend", touchHandler)
window.addEventListener("touchcancel", touchHandler)
window.addEventListener("contextmenu", contextMenuHandler)

<pre id="logger"></pre>

And I got these results, when pressing for a bit without moving the finger:

1. When I default prevent both touch events and the contextmenu event:
   • Chrome logs:

     touchstart
     contextmenu
     touchend

     Note that Chrome vibrates at the same time contextmenu is fired.
   • Firefox logs:

     touchstart
     contextmenu
     touchcancel

     Firefox cancels the touch event as soon as contextmenu is fired, which is a problem for me.
2. When I default prevent only touch events:
   • Chrome logs:

     touchstart
     contextmenu
     touchend

     Nice. It dosen't vibrate.
   • Firefox logs the same thing. This time, it didn't cancel the touch, but it selected some text.
3. When I default prevent only the contextmenu event:
   • Chrome logs:

     touchstart
     contextmenu
     touchend

     It vibrates and scrolls, however.
   • Firefox logs:

     touchstart
     contextmenu
     touchcancel

     Again, it's canceling the touch, but no text is selected.
4. Finally, when no events are default prevented:
   • Chrome logs:

     touchstart
     contextmenu
     touchend

     And still vibrates and scrolls.
   • Firefox logs:

     touchstart
     contextmenu
     touchcancel

     Same thing :(

So, is there any way to prevent scrolling, context menus, vibration and selecting text, and to avoid Firefox canceling the touch?
