> Alternatively, we can give a feedback to W3C that we should have exactly one reference file per test. What's the purpose of having multiple references anyway?

Answer: "In some cases when creating the reference file, it is necessary to use features that, although different from the tested features, may themselves fail in such a manner as to cause the reference to render identically to a failed test. When this is the case, in order to reduce the possibility of false positive testing outcomes, multiple reference files should be used, each using a different technique to render the reference. One possibility is to create one or more references that must not match the test file, i.e.: a file that renders in the same manner as a failed test."
