Hi, I think "BIZ UDGothic" is not a mono-width font and therefore not supported by ACE (See #460).

Can you confirm this bug is still there when using the default font?

@skillcrushbinguyen when scrollbar appears the wrapping changes in textarea and other editors as well. Which behavior do you expect instead of that?

[skillcrushbinguyen]

@nightwing My expectation is that the line will not break when the scrollbar appears. In the demo above, the character 91 should persist in the first line

But then where should the scrollbar go? it will either cover the text or editor size will have to change, or we would have to reserve space from the start and always display 91 on the second line.
