Issue 206 fix

This commit fixes the issue #206 about font problems with floating blocks containing text.
It was due to a deleted line in a previous commit https://github.com/flyingsaucerproject/flyingsaucer/commit/b8b20dc56185764eb2348153d1694b169f07fdef#L0L564 on purpose or not. I put that back to fix the bug.
