Mobile TextArea component loses HTML formatting with View change or Style change

Steps to reproduce:

1. Using a Mobile TextArea component set the htmlText property of the StyleableTextField display of the TextArea component. eg.

StyleableTextField(main_txt.textDisplay).htmlText = "<b>HTML</b>";
note: TextArea requires skin class: spark.skins.mobile.TextAreaSkin

2. Change a style on the TextArea such as Font Size or Font Type. eg.

main_txt.setStyle("fontSize",25);

3. OR change to a new View and return to previous View with destructionPolicy="never"

Results:

HTML formatting like font color and size is removed.
