Hi,
don't know if that be any of help, but I run below scenario with SATA 
and NVMe drives. For me, the issue is reproducible on NVMe drives only.

Scenario:
1. Create R5D3 with native metadata
     # mdadm -CR /dev/md/vol -l5 -n3 /dev/nvme[0-2]n1 --assume-clean
2. Create FS on the array
     # mkfs.ext4 /dev/md/vol -F
3. Remove single member drive via "--incremental --fail"
     # mdadm -If nvme0n1

The result is almost instant.

Thanks,
Mateusz
