[BUG] Firefox TouchStarted not working

Most appropriate sub-area of p5.js?

• Color
• Core/Environment/Rendering
• Data
• Dom
• Image
• IO
• Events
• Math
• Typography
• Utilities
• WebGL
• Other (Touch? User Interaction?)

Details about the bug:

TouchStarted is not registering in Firefox

• p5.js version: latest? also web editor and react-p5 and therefore (devDependency) 1.0.0?
• Web browser and version: Firefox! (77.0.1 - latest) but not on chrome...
• Operating System: Windows, (not android - tested)
• Steps to reproduce this:
  2 Ways I tested:
  • The hard way: With react and react-p5
  • The easy way: on the p5 editor in a new sketch type:

    function setup() {
      createCanvas(400, 400);
     }
  
    function draw() {
      background(220);
    }
  
    function touchStarted() {
       console.log("Touch started"); 
    }
  

  I expected it to log "Touch started" but it does not do that. (mousePressed however works)

Start with the p5 editor sketch using touchStarted() and compare its behavior in Firefox 77.0.1 with Chrome, where mousePressed() works. Trace the touch event entry point and verify that the example logs "Touch started" in Firefox without regressing mousePressed().
