Enabling this callback:
quickly leads to an error - a double deregistering of a GCpointer in the MakeCode GC. It is due to subtle race condition and the fact that CODAL eagerly calls the delete listener callback.
The fix is to codal-core: lancaster-university/codal-core#188, which explains the scenario in more detail. Once we have a new version of codal-microbit-v2 incorporating the fix, we can point to that and eanble the callback.
