Ok, that took a lot of digging to spot that the clip wasn't being performed at
all..

commit b6daf47fa08c74d9672040b2b98ac6dd1f841429

    spans: Do not assume that we manage to perform the clip geometrically

    Even for bounded masks, we may fail to perform the clipping
    geometrically for a variety of reasons, the prime one being that the
    clip has a mixture of antialias settings. So when compositing the
    polygon, we need to check whether a clip path still remains and so
    requires a clipmask.
