Unfortunately, I've had to back this patch out again as it has caused
errors in the CI over the weekend e.g. [1]. No errors were reported with
the patch before I merged it, but I see now that not all tests were
successfully run on it. Can you please take a look at the CI errors
reported and submit a new version of this patch.

Thanks,
