Whoops, no it doesn't... I checked more closely and there is another error:<br>

So maybe something else in my code has been broken by recent changes. <br>
It's a bit hard to come up with a minimal example because for these <br>
dual-porosity meshes it is doing some fairly complex low-level surgery <br>
on the DMPlex, to add the "rock matrix" cells "inside" the existing cells.<br>
