fix(react-dom): check if iframe belongs to the same origin

Accessing the contentDocument of a HTMLIframeElement can cause the browser
to throw, e.g. if it has a cross-origin src attribute.
Safari will throw an uncatchable error when the access results in "Blocked a frame with origin". e.g:

```javascript
try {
 $0.contentDocument.defaultView
} catch (err) {
  console.log('err', err)
}

> Blocked a frame with origin X from accessing a frame with origin Y. Protocols, domains, and ports must match.
> err – TypeError: null is not an object (evaluating '$0.contentDocument.defaultView')
```

A safety way is to access one of the cross origin properties: Window or Location
Which might result in "SecurityError" DOM Exception and it is compatible to Safari.

```javascript
try {
 $0.contentWindow.location.href
} catch (err) {
 console.log('err', err)
}

> err – SecurityError: Blocked a frame with origin "http://localhost:3001" from accessing a cross-origin frame. Protocols, domains, and ports must match.
```
