Does it occur on multiple sites: N/A

Is it a problem with a plugin? N/A 

Did this work before? N/A 

Does this work in other browsers? works in Firefox

Dean, with this:

transition: -webkit-filter 0.3s;
transition: filter 0.3s;

should we be smart enough to ignore the second rule with the invalid transitioned property name?

It seems the solution is to use a comma separated list of transitions, instead of expecting the supported transition property to overwrite successfully:

Safari and Chrome agree on rendering for this test case. I don't believe there is any remaining compatibility issue.
