Copy & Paste breaks Undo/Redo

[anthonyjb]

That latest upgrade to support HTML copy & paste appears to have broken the Undo/Redo functionality. To reproduce the error:

• Select an editable paragraph
• Write some content
• Copy some HTML content into your clipboard
• Paste the content into the page
• Attempt to undo the action

The history stack seems to be reset on the paste action. I'll look to resolve and get a patch out this weekend.

I can't now reproduce this - I need to track down the issue I was finding again :/
