D3 Examples - dc.js dynamically add class to dc.SelectMenu; IE11 issue

dc.js dynamically add class to dc.SelectMenu; IE11 issue
When dynamically adding custom css classes to a dc.selectMenu IE11 kicks them out when filters are applied. For now I push them in again using a renderlet. This causes "glitches"/moves content around due to added padding or widths/heights.
~~Is this a bug? Does anyone know a cleaner workaruound not causing these glitches to appear?~~
