I ran into a really strange issue that only occurs within AIR applications (AIR 1.5.1/1.5.2). When I create a TextField control, set it's style, and then assign it HTML text it appears fine. However, if I wish to reset that TextField content and the original content has links, the entire replaced content becomes one HTML link. I think the issue can be better explained with some images and some code samples.
