Undo/Redo: Different behavior between desktop and mobile browser

[Xanatos84]

Hello,
on desktop chrome browser undo and redo operations always just change one input letter per click. On a tested iPhone with mobile Safari browser undo and redo changed not single letters but whole words per click. Correct behavior should be, that they also change on mobile browsers just one letter per click.

Another problem I could observe was, that when there are more than one kolkov-editor where used in a page, the undo and redo operations also changed user input of the other editor, when the changes of their own editors were finished. I assurred, that both editors have their own ids and separate configurations.

I hope I explained the problems sufficient.

Kind regards
Florian
