[Violation] Added non-passive event listener to a scroll-blocking 'touchstart' event. Consider marking event handler as 'passive' to make the page more responsive.

[goto40]

I created a small single-page app with a canvas inside, for which I setup a kaplay configuration.

However, I get [Violation] Added non-passive event listener to a scroll-blocking 'touchstart' event. Consider marking event handler as 'passive' to make the page more responsive. warnings (similar for 'touchmove' and 'wheel').

I tried to set passive: true, but then I get errors when kaplay uses preventDefaullt... I do not understand why I do not get these warnings when kaplay is alone and not embedded in my single-page app.

Thank you for your help...

The solution 1 described by tao on stackoverflow works for me. I just added "wheel" to the list of callbacks to be patched.

Is this a bug?
It seems to originate from here in kaplay. We could change certain event listeners to be passive? Or does this break something? In this case maybe an option to make them passive here could help?

I am open for suggestions.
