I don't get your meaning by "fix the input event propagation". My change fix the following example. Checkout if it is what you mean <html>
<body>
<script src="../../../build/node_modules/react/umd/react.development.js"></script>
<!-- The latest version on unpkg won't work on this example. -->
<!-- <script src="https://unpkg.com/react-dom/umd/react-dom.development.js"></script> -->
<script src="../../../build/node_modules/react-dom/umd/react-dom.development.js"></script>
<script src="https://unpkg.com/babel-standalone@6/babel.js"></script>
<div id="container"></div>
<custom-element>
#ShadowRoot: open
<div>
<!-- React mount on this node, not the ShadowRoot -->
</div>
</custom-element>
<script>
var s = document.querySelector('custom-element').attachShadow({ mode: 'open' })
var d = document.createElement('div')
s.appendChild(d)
</script>
<script type="text/babel">
function Comp() {
const [s, ss] = React.useState('input')
return <span>{s}<input value={s} onChange={e => ss(e.target.value)} /></span>
}
ReactDOM.render(
<Comp />,
d
);

cc @trueadm on this one |

It seems like jsdom doesn't support shadow dom ( jsdom/jsdom#1030 ) so I can't write a test for that |
|
Looking at this again, it clashes with some of the work we're looking into now in regards to moving event registration away from the document and to roots instead. I'd rather come back to this PR in the future (if needed). |
fc01ed9 if so, can you cherry pick this commit at least? |

In 62861bb#diff-adeaf9850a891faf89a84c73308e0e0bR284 @trueadm mentioned:
Why? Rejecting document fragments will disable the ability that React to render in a ShadowRoot. |
|
@shivaylamba @trueadm I have rebased this PR. Due to conflict with React new event system, the other 3 commits are removed. Only ce0f272 (fix Again, why throws on document fragments container? It's useful when trying to wrap the React component into a web component. |
