I did a little bit of reading around and I found this. Seems like it has something to do with the version that you are using? I also can assume that it will be fixed sooner or later. I personally do not know much about p5, and how you could work around this issue, but I do know that in general you could make a button with HTML, and then use JavaScript and the onclick() function to do something similar?
Hopefully this helps,
