If the TimeSpan in the TimeSpanUpDown control is set to a value larger than 23:59:59 via binding, then the display of the TimeSpan is corrupt. The TimeSpan is correctly displayed, but then the 'hh:mm:ss' part is appended to the end a 2nd time.
As detailed [here](https://stackoverflow.com/questions/33300212/workaround-for-display-bug-of-timespanupdown-when-changing-days) , this can be reproduced by adding two TimeSpanUpDown controls to a form and binding them to the same time span value. When one is changed, the second is updated via a property changed notification and ends up showing incorrect timespan, as per the picture.
