QSplashScreen's showMessage() misplaces message

QSplashScreen's showMessage() misplaces the message when the message contains embedded HTML formatting codes. For example,

const Qt::Alignment pos = Qt::AlignBottom | Qt::AlignRight;
splash->showMessage(QObject::tr("<b>Creating Main Window...</b>"), pos, Qt::black);

will display the message in the upper right corner with the flags, and works correctly if they are not present in the text string.
