--- Comment #7 from Terje Bless <link at pobox.com> ---
Since the original bug is a bit short on a description, I'll try to summarise: empty elements with display:inline return an incorrect .offsetTop. Setting the same element to display:block makes .offsetTop() return the correct value. @ksev's original attached test case demonstrates this (alteredOffset.top is the element manually set to display:block, anchor.offset().top is the display:inline version).

This bug is still present as of whatever WebKit version is in Safari 11.1.2 (13605.3.8), and it bit me in production on one of the Wikimedia project sites (English Wikisource). As best I can tell there's no really good workaround: if you have a empty inline element it's probably for a good reason, and either adding filler content or turning it into a block element will be at best awkward (and in my particular case, I have no influence over the layer of the stack that's generating the HTML).

Can also confirm this is still working correctly in latest Firefox, and in IE11 (which is what I happened to have lying around). Latest Chrome, however, has the same bug.
