el.clientHeight == 0, preventing resizing

[aeoncleanse]

process (Textfit.js:137)
TextFit._this.handleWindowResize (Textfit.js:77)
call (throttle.js:26)
throttled (throttle.js:36)

I have no idea why, but no matter what I do to the parent, or to the Textfit element itself with styles, the element's clientHeight appears to follow a pattern of X, 0, 0, X, 0, 0 etc when resizing a window. Perhaps something to do with the throttler?
