Vis timeline negative Arabic dates not displayed properly

[aowss]

Negative Arabic dates are not displayed properly when combined with the month ( even though they are displayed properly when they are alone ): the negative sign should be on the left of the number, not on the right between the year and the month.

The options is as follows :

    format: {
        minorLabels: {
            year:       'Y'
        },
        majorLabels: {
            weekday:    'MMMM Y',
            day:        'MMMM Y',
            week:       'MMMM Y',
            month:      'Y',

        }
    }

The negative sign is also on the left ( but even with the year alone ) if a enable the right to left behaviour.
