Yes it does, separators must separate things.
border-image: // 10px
(or border-image: / / 10px) is also a bad unless it means
border-image: <nothing> / <nothing> / 10px

As <nothing> is not an allowed value, something else than '/' ou ',' 
(defined as separators) should be used, unless you add specific rules like 
"don't start with a / and don't put two / in a row", or even add an 
'ignored' value.

(and the fact that it happens also in border-image is a new issue, linked 
to the original one on 'background').

Baroula que barouleras, au tiéu toujou t'entourneras.
