Support 'passive' option on event listeners

[goswinr]

Describe the bug

Most DOM events are not passive by default, but some are ( wheel, scroll, ..) .
see https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/addEventListener#passive
And it is not consistent among major Browsers.
Should Solids JSX support explicit passive options for event listeners ?
See how React addressed this issue: facebook/react#6436 and the resolution: facebook/react#19654

Steps to Reproduce the Bug or Issue

see example on SolidJS Playground and below: (update Sep 2024: on chrome the playground doesn't show the bug anymore)

import { render } from "solid-js/web";
import { onMount } from "solid-js";

function Counter() {  
  const wheel = (e:MouseEvent) => {
    e.preventDefault() // only works on not passive events
    e.stopPropagation()  
    console.log("wheel stopped?")
  }

  let div ;
  onMount(() => div.addEventListener("wheel", wheel, {passive:false}) ) // most events are not passive by default but "wheel" is in Chrome

  return (
    <>
    <div oncapture:wheel={wheel} style={{"background-color":"lightgreen","height":"26vh"}} />
    <div ref={div} style={{"background-color":"lightgray"  ,"height":"26vh"}} > In Chrome this gray div is the only div that prevents scrolling</div>
    <div on:wheel={wheel} style={{"background-color":"lightblue","height":"26vh"}} />
    <div onWheel={wheel} style={{"background-color":"crimson"  ,"height":"26vh"}} />
    </>
  );
}

render(() => <Counter />, document.getElementById("app")!);

Expected behavior

Like on:* and oncapture:*
There could be a JSX syntax to specify the passive option for events. Maybe onpassive:* and onnotpassive: * or onWheelNotPassive and onScrollNotPassive

Great suggestion. How are other frameworks handling it. Love to see some inspiration for this feature.

This is very important. Otherwise, do we have to use addEventListener temporarily?

[goswinr]

@chaosprint yes, currently you have to use el.addEventListener("wheel", handler, {passive:false}) so that preventDefault() works in the handler.
