Lazy-pulling fail when first pulling

[wswsmao]

Hi，I found that Lazy-pulling fail when first pulling，this is my command:

# convert org image to estargz image
$ nerdctl image convert --estargz --estargz-min-chunk-size=37625 --oci abushwang/itex:org abushwang/itex:esgz-chunk37625

# push it to my dockerhub
$ nerdctl push abushwang/itex:esgz-chunk37625

# clean local images
$ nerdctl images -q | xargs nerdctl rmi
$ nerdctl system prune

# lazy pull
# from this log we can find that nerdctl downloaded the complete image
$ time nerdctl --snapshotter=stargz run -it --rm abushwang/itex:esgz-chunk37625 echo 'hello, world!'

I am confused why the lazy pull did not work at first pull
