Description

Steps to reproduce:
1. Open the attached .swf file
2. Note there is no trailing newline after the last line in the editable TextArea
3. Click the large button to set the htmlText to a slightly altered version of itself
4. Note that now there is a trailing newline after the last line of text.
5. remove the trailing newline and return to step 3 to repeat

Actual Results:
a miscreant newline is added to the textArea when it's own input is read

Expected Results:
the text should be left unchanged.

Workaround (if any):
store the number of characters that should be in the TextArea, and after applying the htmlText and calling text_area.validateNow() check to see if there is an extra character. If so, remove it like this (for a TextArea named text_area):

text_area.setSelection(text_area.text.length-1, text_area.text.length);
text_area.replaceSelectedText('');
