The issue seems to be affecting jQuery UI too:
jquery/jquery#2828

After further investigation, it seems that $.position() method is broken in IE11. The affected jQuery versions are 1.12.0 and 2.2.0. According jQuery team, they will fix the issue in a patch version 1.12.1 - jquery/jquery#2836 (comment)

Based on this, we will not fix that part on our side, as patching the code for particular jQuery version will be impossible to maintain.

Workaround: Until the issue fixed on jQuery side, use an older jQuery version (1.11 for instance).

Note that this also affects Google Chrome 47 on Ubuntu 14.04 64bit in some way, not just IE.
