[plt-scheme] Return in Interactions pane

Say I have the following few lines
Welcome to DrScheme, version 206p1.
Language: (module ...) custom.
> (define (square x) (* x xx))
> (square 5)
 reference to undefined identifier: xx
>

This is quite understandable - a misspell
So I move the caret to the end of the line (define (square x) (* x xx)) and
press return. On v205, that would copy (define (square x) (* x xx)) to the
end of the current input line. In v206, this only moves the caret there. Is
this a bug?
