What steps will reproduce the problem?
1. Launch chrome, open to NTP and open DevTools.
2. Go to 'Console' section and click on 'Create live expression' button.
3. Type any text in 'Expression' text field.
4. Select the text and right click on it to open context menu and select 'Undo' option.
5. Now Observe the last character entered.
 
Actual Result: 'Undo' option works for 2nd last character instead of the last character of any text from second instance.
