Another undo bug

[richienyhus]

From GCI2012: Edit something in the middle of a text. Select the text and apply any style(html tag from the buttons) on it. Now click the undo button.

It seems that the undo/redo function remebers the last position of the edited text and doesn't count the tag you apply as an action. As a result when you undo, it goes back to the last position of the text before every new html tag you inserted and that is wrong.
