When searching for a manifest digest in the tag list view, matches in child manifests of manifest lists are not found.

For example: https://quay.io/repository/microcks/microcks-postman-runtime?tab=tags&tag=latest and search for the SHA digest beginning `31bc124` should match the amd64 variant of the tag 0.6.0: https://quay.io/repository/microcks/microcks-postman-runtime/tag/0.6.0?digest=sha256:31bc124feddd47633646b9845a27b45118d396ac41570b3a739d932c7c16c26c

But it doesn't. The search comes up empty. It seems child manifest digests are not included in the digest-based search. This happens in both the Angular and PatternFly UI.
