Hmmm... yeah, I actually did create such a button and while the images had clearly loaded and were displayed the textHeight still didn't take them into account... I also tried getting an actual reference to the sprite representing the img tag within the html using the getImageReference method of the textArea's textField member. The height and width of the sprite were way larger than the actual height and width of the image for some reason... not sure why.
Unless anyone has any other ideas I think I'll resort to regular expressions to parse through img tags and just use mx:Image... (In my particular use case I'm either getting a single image link or some text so that will do for me...).
