The reason why your test case breaks is because it's spelled "visible" (not
visable) — changing it to visible makes the JavaScript detect the property
correctly.

Nonetheless, the behavior is still incorrect: adding a test case that shows
this in a different way.

The combination of overflow-x: visible; overflow-y: hidden;  (or vice-versa) is
a desirable combination and should behave exactly as it reads: elements
expanding outside the containing "viewport" should only be rendered along the
x-axis but not along the y-axis.

What doesn't get defined by the spec, however, is what happens to content that
is outside _both_ x and y axes. Should elements always get clipped to exact
rectangles? (by far easiest to implement) Which axis/setting gets precedence?
Letting it be dependent on CSS property order AND allowing for non-rect
rendering would be very tricky to implement I'm sure.
