Links become unclickable when their css has z-index < 0 and position isn't static. This is easily reproducible and happens everytime. When either of those css-properties is removed then clicks become clickable again. Could be related to https://bugs.webkit.org/show_bug.cgi?id=21675

Filed bug #26582 which is related. Adding "html { margin-top: 3em }" to the CSS in the testcase above moves the root element out of the way, enabling the hyperlink to be clicked. However, changing the z-index of the html element to "auto" or "-100" does not make the link clickable.

Filed related bug 73068 : absolutely positioned div that is initially onscreen (ie not requiring scrolling to see) does not have hover applied to it (thanks ap@ for the pointer to this bug).

WebKit and Blink continue to agree on this behavior, Firefox is the outlier.
