Hi,

in the Visual Editor Sandbox, when you indent and then undo, the WYSIWG display doesn't show the indentation undone.

More precisely:
1) I write some free text in a text only paragraph
2) then indent items of an existing list outside the text paragraph using the indentation button
3) then I hit undo

What I expect: The indentation is undone.
What happens instead:
a) The text is removed (i.e. the second but last action is undone)
b) but the indentation remains.
c) More undo clicks will just go on undoing actions before the indentation.

After going a few times back and forth using the undo and redo buttons, the editor seems completely messed up:
d) I cannot add further new lines at the end of the page
e) The blinking cursor lags by one character (i.e. when I type "david", the cursor will be between i and d)
f) Eventually, the characters I type are no longer displayed, though the blinking cursor moves when I type (even advances from line to line without me pressing enter)

Speculation: When I show the preview view after step 3), the indentation has correctly been undone there (in addition to other actions having been undone). So maybe this is a bug only in the display part, since the code is apparently correctly changed.

Best,
David
