Operating System

Steps to reproduce this
Steps:
- Open https://editor.p5js.org/Michal8705/full/PaTRVm7UP on Chrome
- When I roll up the top bar with a quick movement (screen1), then in the text field is all the time false and touching event did not work (screen2). In iOS without this action all the time text information is 'false'
Does anyone know how to solve this problem or maybe a fix in p5 is needed?

Research direction
Reproduce the linked full sketch on Chrome 101 for iOS 14.7.1, comparing normal use with quickly hiding the top bar. Read the linked sketch and editor example to identify how the touch state is reported. Done means establishing whether p5.js causes the state to remain false and documenting or correcting the behavior accordingly.
