Checking the log of an action which is using the following

- uses: actions/checkout@v4
  with:
    submodules: true
    fetch-depth: 0
    filter: blob:none

The submodule checkout step indicates the filter is not applied

# Fetching the primary repo
git -c protocol.version=2 fetch --prune --no-recurse-submodules --filter=blob:none ...
# fetching / checking out submodules
git -c protocol.version=2 submodule update --init --force

I was expecting to see the --filter=... also present in the submodule update step. Is there a reason this is not the case?
