Freeze on touch in mobile browsers

IDE: 2023.8.2.108
Runtime: 2023.8.2.152

When game runned in mobile browser (or in desktop google chrome in mobile-mode) it freeze every time player touch the screen.

I found several forum posts with the same problem, but no one found a solution.

I tried replacing the HTML5 Runtime with what is currently in this repository but problem repeated.

I alos tested few games I found on itch.io (with tag gamemaker) and all have problem with touch on mobile devices.

Hello, is there any news on fixing this problem? My HTML5 games are unplayable on mobile devices, although they work fine in the browser on a PC. When I press and hold on the game window area, I feel a vibration feedback, like I'm selecting text in a browser. The previous tips don't help at all.

@OneOnlineShow I haven't checked yet, but there is a possible solution:

Some people report that adding the following to Code Injection in a new extension helped, which is likely similar to what was proposed with touchAction

<GM_HTML5_PreBody>
    <script>
        document.addEventListener('touchstart', e => {
            e.preventDefault();
            }, {passive: false})
    </script>
</GM_HTML5_PreBody>

This works but then it breaks the "clickable_add()" buttons for touch. And I can't use any touch actions outside of the game canvas. Just something to be aware of.
