TextColor does not work for <b>-tag #32

Hi,
I am currently using a FlowTextView to display a white text. I am now trying to add bold text to it, but the new text is unfortunately not colored accordingly. Does anybody have an idea on how to achieve a white and bold text with this component?

e.g.
ftvDescription.setText(Html.fromHtml("HeadlineLorem ipsum"));
ftvDescription.setTextColor(getResources().getColor(android.R.color.white));
