Font bold button doesn't work when an indent is set for the text.
To reproduce, try the following:
1. Run Ensemble8.jar.
2. Go to Controls -> HTMLEditor sample.
3. Select a portion of text, and press bold (B) button. The text becomes bold (works with default font - Segoe UI).
4. Now press an indent button (its graphic is four lines with an arrow to the right).
5. Select another portion of text, and press bold button. Nothing happens.
