Hi
While playing on iPhone SE 14.8.1 whole canvas selected likes text selection. It happens when frequent taps are done. Once this issue occurs, it persists on every screen and player has to force close the game as the buttons interfere with player interaction

Tapping and holding down the finger for around 2 seconds causes the screen to be… highlighted in iOS on multiple devices. We have used multiple CSS tricks to resolve the issue but to no avail. The issue is effecting both of our games https://www.blockletegames.com/ https://rareboards.secondlegion.com/ particularly we discovered the bug while testing the darts game, since in the mechanic you have to tap and hold the "Throw dart" button so the power needle goes up and you release it to throw the dart. The highlighting make the game unplayable. We also tried to reproduce in a base Starter Kit: Model Viewer project and also reproduced it here: https://drive.google.com/file/d/1pHfDIioJZOu3sxOPDeDKkEwHgMc82zDO/view This is on iphone X with iOS version 14.2 The weird thing about the bug is that only if you tap and hold the **left side of the screen** then the bug occurs, while on the right it doesn't. This is what happens, Right side give haptic feedback like it wants to highlight, but no highlighting occurs. Left side gives haptic feedback AND highlights. When the screen gets highlighted, there is no way to un-highlight it (other then reloading the page) The bug has occured on the following devices and browsers; iphone X 14.2 Chrome and Safari iphone 11 14.2 Safari Also we are not not sure if it happens on older iOS versions. The bug does not happens on a android device. Steps to reproduce: 1) Run chrome/safari on a iphone having 14.2 2) Run https://playcanv.as/p/nJ0wkUD4/ (Project: https://playcanvas.com/editor/scene/1055110) 3) Tap and hold your finger on the left side of the screen for around 2-3 seconds.
