• Can still edit text boxes / textareas and press undo and have the browser based undo work.
• Can still edit our own custom editable dom elements (rename a view/group/table/application and press undo whilst the cursor is blinking, the edit should be undone by the browser with no popup until you click out of the edit mode)
