There's another bug where if you add multiple RTF text sections in succession, it will retain the color from the first section used.
For example, you can modify the "RichParagraph" example to load RTF from not one, but two files, say "Example.rtf" and "Example2.rtf". If "Example.rtf" has text in green and "Example2.rtf" has text in blue, both sections will show in blue.
