Try this approach

Copy the portion of the text that is represented by the current scrollbar
position in the original field
 into an identical hidden fld , the apply the htmltext to the original and
the hidden copy.  Now get the formattedHt of the copy and calc the correct
scroll value of the original.

I hope this is what you are after.
