Thanks for the patch!


We should also have a dedicated test with an unused interleave group, to test the patch. Could you add a target-independent one? Both the new test and the test changes in this PR should probably be submitted via a separate PR first, so the current PR then only shows the difference caused. by the patch (i.e. removed the dead interleave group from the new test)
