Core Header Scroll broken when building on crosswalk

[Shaul Hadar]

Hi, I tried some stuff with polymer, and after a few checks, i tried to build a demo of the header scroll parralax effect with a crosswalk build, and for some reason it didn't work.  I could build the tabs example with no problem, but this didn't work well for me, did anyone try to build this kind of test in crosswalk and has any information about this perhaps?

thanks :)
