'use strict';is needed at the start of the enclosing block, but we don't have control over that since the code we submit is pasted in the middle of the actual script being executed by the server. Need to wrap it in a function, declare strict then call the function. Which is too much work, so just usevar.EDIT: I'm wrong, you can just add
'use strict';at the top. Maybe the submission is being enclosed in a function.Add Reply Preview cancel
