Wrong Y coordinate position reported when cursor is on last character of first line

[sandeep45]

If i am on the last character of first line, it will report Y-cordinate of the second line.

The change made doesn't work for me, but if I remove it, the position returned for the caret is correct.

You can verify this by using the demo jsfiddle, just write the word "test" a few times until it wraps to the next line, then move the caret to the beginning of the second line. The position will be shown to be at the end of the first line instead.

This happens in Google Chrome (latest stable release, 29.0.1547.57). In Firefox, the position seems to be wrong with or without the change in wrapped lines.
