Can someone have a look at this bug? As it stands, it is impossible to tell (from JavaScript) whether an element is visible or completely clipped.

Currently, when an element has no "clip" CSS declaration, getComputedStyle correctly returns "auto". ("auto" meaning the element is not clipped)

But when an element has "clip: auto" or "clip: rect(auto, auto, auto, auto)", getComputedStyle returns "rect(0px 0px 0px 0px)". This is a valid clip value, but this value means the element is completely clipped.
