p5js/hydra mouse and key events do not work in the editor

[taconi]

I had this problem when working on #318. The mouse/keyboard events weren't being triggered.

The events are only sent when I'm outside the editor, but the only parts of the site outside the editor are, a small space at the top of the page between the button to change the target and the settings button and some parts of the edge of the site

p5 = new P5()

p5.draw = () => {
  p5.fill(p5.mouseX/5, p5.mouseY/5, 255, 100)
  p5.rect(p5.mouseX, p5.mouseY, 30, 150)
}

s0.init({src: p5.canvas})

src(s0).out()

shape()
  .scrollX(() => mouse.y / 1080, 0)
  .rotate(() => mouse.x / 1920, 0)
  .out()
