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 http://jsbin.com/lodika/1/edit?html,js,output
