By quintesse:

There is no "policy", I normally just do it for issues, especially if it's more about the interaction between several kinds of features (which is *not* the case here I agree). But in the end it's often just to see the issue displayed in a single obvious test case. But it's something I do, not necessarily something to copy ^^
