The "auto" behavior of the "cursor" property used to be only vaguely defined, but to improve interoperability, the latest specification is more clear:
> auto behaves as 'text' over text, and 'default' otherwise.
Other expected effects, such as the "pointer" cursor over links should be achieved using the UA stylesheet, rather than through the magic behavior of the "auto" value.
Webkit uses "auto" rather than the UA stylesheet to adjust the cursor, which causes the following tests to fail:
This is now being fixed in Chrome, it would be good if Webkit fixed it as well. See https://bugs.chromium.org/p/chromium/issues/detail?id=737452
