Click events in undo/redo manager

Hi @artf, I have a issue regarding undo manager and I have checked it's also on your demo page. Problem is that undo manger also count the event when we click on outside the editor section like on the layer button, style button, Block button or any other button which are on top. So if we add a text and then click on layer button after that style button and after that on block button and then we drag a link then it consider as 5 events so if we have to revert back to the text then we need to click on 4-5 times. I also want to know is it a issue or you have added that events on the undo and red...
