AIR: Images do not display using <img> tag in htmlText on Text or TextArea components

Steps to reproduce:
1. Create an AIR project in Flex Builder containing a Text or TextArea element with htmlText
2. Run the application

Actual Results: Image displays according to the src attribute on the img tag (both external and internal images)

Expected Results: Nothing is displayed (the img tag contains no innerHTML, so only whitespace is shown

Workaround (if any): Use the AIR HTML component instead of Text or TextArea (this is a weak alternative, as you lose some of the interaction available to the other components.

Notes: Example attached. Also, this is a really annoying problem because the documentation makes no mention of the img tag failing to work in AIR (especially external images).
