Snakemake version
Occurs in v9.1.1 (and older)

Describe the bug
snakemake seems to arbitrarily ignore the ancient() setting in rule inputs when sub-workflows are called using the module: functionality.

Minimal example

In the case below, rule inputs with ancient statement within module_hydropower may be re-triggered, even if the file exists.

configfile: workflow.source_path("./test_config.yaml")

module module_hydropower:
    snakefile:
        "../../workflow/Snakefile"
    config:
        config["module_hydropower"]

use rule * from module_hydropower as module_hydropower_*

rule all:
    message:
        "Generate CF timeseries for a small country."
    default_target: True
    input:
        "results/by_shape_id/hydro_dam_cf.parquet",

Additional context
This issue was identified in this PR calliope-project/module_hydropower#1

Here is a failing example: module_hydropower.zip. You should be able to re-run our case by running the test workflow in tests/integration

This project uses data that requires a specific API key. To allow for CI tests (and to deter constant downloads) we use ancient in rules that would re-download data using the API, and include minimal test datasets in the integration test. Unfortunately, snakemake is ignoring these pre-existing files during github's CI testing, leading to the failure.
