GridFunctionSpace update error when using LexicographicOrderingTag

I am using a Taylor-Hood GridFunctionSpace in 2d exactly as in the detailed description here, i.e a CompositeGridFunctionSpace consisting of a PowerGridFunctionSpace with two P2 GridFunctionSpaces for the velocity and a P1 GFS for the pressure. After doing a global refine and updating the GFS, the pressure subspace still has the old size. This only happens when I use LexicographicOrderingTag as the ordering tag for the CompositeGridFunctionSpace.

I adapted the test case from #70 (closed) to this failure, you can find the files here, the build instructions are the same as in #70 (closed).
