There seems to be indeed a bug in IE that it is confused by a
position: relative somewhere inside a div that provides scrollbars.
The workaround seems to make sure all intermediate containers have
position: relative.
The latest git version contains a fix that makes your example work
properly on IE.
Alternatively, you can patch your example in the following way (which
results in the same workaround):
