<pre>Yosemite 10.10.3
Safari 8
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
