I came across jquery/jquery@0bf499c which links to mishoo/UglifyJS2#2198. Apparently the default compression config of UglifyJS possibly produces code incompatible with IE10. I thought that this might possibly be relevant for this project here since IE10 is also supported (as discussed in #21416 (closed)).
No idea whether this would really change anything in the output, maybe the constructs which would trigger this (something with typeof) aren't even used but better safe than sorry. (Also, it might prevent problems in the future, especially if jQuery should get ditched).
