sops seems to duplicate yaml comments in certain cases

I have no idea how many cases this happens in, but I found at least one case where sops duplicates comments in yaml files.

I'm able to reproduce this with the following steps.

First create a yaml file with the following content:

a:
    b:
        c:
            - name: test_1
              test: a
            # I get duplicated
            - name: test_2
              test: b

Then encrypt it with sops.

$ cat test.yaml
a:
    b:
        c:
            - name: test_1
              test: a
            # I get duplicated
            - name: test_2
              test: b
$ sops --version
sops 3.7.1 (latest)
$ sops -e --verbose -i test.yaml
[GCPKMS]	 INFO[0000] Encryption succeeded                          resourceID=REMOVED
[CMD]	 INFO[0000] File written successfully

Now decrypt it with sops.

$ sops -d test.yaml
a:
    b:
        c:
            - name: test_1
              test: a
            # I get duplicated
            # I get duplicated
            # I get duplicated
            - name: test_2
              test: b

Reproduce the report with the provided test.yaml content using sops 3.7.1, then trace the YAML encryption and decryption paths responsible for comment handling. Done means decrypting the example emits the comment once rather than duplicating it.
