Shell command incorrectly shows as None for dryrun when using run directive in snakemake rule

[tbenavi1]

Snakemake version
My version of snakemake is 9.5.1.

Describe the bug
Here is an example rule that triggers the bug:

rule link_or_gzip:
  input:
    get_hap
  output:
    "results/{sample}/{sample}.{hap}.fasta.gz"
  threads: 1
  resources:
    mem_mb=50000
  run:
    if str(input).endswith(".gz"):
      shell("ln -sr {input} {output}")
    else:
      shell("bgzip -c {input} > {output}")

This rule will run one of two shell commands depending on whether the input is already gzipped. However, when doing a dryrun "-np" the output for this rule shows "Shell command: None". Obviously, the pipeline knows what shell command it is supposed to run. It would be great if the dryrun could also show what shell command it is going to run. Thanks.

Unfortunately the shell() function in a run or script is a bit different than the shell directive as it relates to writing the command out to logs. Work was started towards handling this in #3397, but has become stale. I can look into this when I have some time.
