Uncaught ReferenceError: headerHeight is not defined

[FreekyMage]

When resizing the window this error keeps popping up, but it doesn't seem to break anything luckily. The error itself is in the eventThrottler function. For now I have encapsulated the code in an if statement that checks if the variable is undefined.
Only tested in the latest chrome version for now.

I get the same problem and made a fiddle for this: https://jsfiddle.net/pgup19mc/13/

By resizing the window, we get the error "Uncaught ReferenceError: headerHeight is not defined"
