Bug: click event is attached to createPortal

[615349]

React version:
16.13.1

Steps To Reproduce

use createPortal will have click event attached to the DOM element automatically

import { createPortal } from "react-dom";

const Modal = ({ children, onClose, open }) =>
  open &&
  createPortal(
    <div />,
    document.getElementById("modal")
  );

this snippet will add click event attached to the element with id = modal
please open chrome dev tool to check

Link to code example:

The current behavior

click event is added on the element

The expected behavior

click event should not be added

EDIT

---

createPortal(
    <h1>This is heading</h1>,
    document.getElementById("modal")
  );

The header is read by jaws (not sure about nvda) as
this is heading, heading level one, clickable

click event should not be added

Is this about nvda announcing elements as clickable even if they aren't actually? I think adding a bit more context why the click listener should not be added would help the maintainers understanding the issue.

FWIW this is intentional to prevent some iOS issue if I remember it right.

#11927 seems to be the reason.

thanks @eps1lon, it is jaws not nvda, but I think NVDA would have same behaviour.
so for example

createPortal(
    <h1>This is heading</h1>,
    document.getElementById("modal")
  );

this is read as
this is heading, heading level one, clickable

please advise

I tested it with latest nvda and didn't have any problems. IMO we should report this to the screen readers and ask for guidance on how to avoid the announcement. I understand that they want to patch up unintentionally inaccessible pages but in this case it is intended and jaws hurts a11y.

We should have a way to tell assistive technology that the click handler is added to leverage event bubbling for event delegation and not to execute user-affecting code directly.

I've just stumbled across this in NVDA version 2020.1 and latest NVDA version 2021.2.
