As you know, TLF is a boatload of code. I don't know how getContentBounds works, but like I said, I believe that input is reflected to the screen on the keyboard event and then later the composition pass happens. Maybe getContentBounds reflects that temporary state. If you look at RichEditableText.as, there might be code that tackles that issue.
