Steps to reproduce:

1. Type into the textarea
2. Dynamically inject an iframe or update the iframe's srcdoc using JavaScript
3. Focus the texarea and undo the last edit

What should happen:
The texarea should go back to the last edit.

What does happen:
The textarea loses its undo stack and doesn't change. This works fine on Chrome and Firefox. I haven't tested on IE.

Here's a JSBin which replicates the issue
