Raphael multiple line in Text to shift downward rather than upward

问题

I am trying to add dynamic text into the raphael paper using textArea and then copying it to the raphael text. The problem is when are multiple lines the raphael text tends to move the starting point upward. Is there a attribute or method i can use to shift the multiple line text to downward?
