Bug description

In p5, you can call fullscreen(true) to enter fullscreen mode. Currently, calling this doesn't do anything in p5.js mode.

Steps to reproduce this

Test this sketch:

function setup() {
  createCanvas(windowWidth, windowHeight);
  fullscreen(true);
}

function windowResized() {
  resizeCanvas(windowWidth, windowHeight);
}

function draw() {
  background(200);
  circle(width/2, height/2, 50);
}

It should immediately enter fullscreen, but it does not.

No response

Additional context

We currently set fullscreen conditionally based on an environment variable, but even if we start not fullscreen, fullscreenable is required in the BrowserWindow settings to allow this to work.

Would you like to work on the issue?
