Warning on hiding already hidden comment

[richja]

Similar to #559, when using hide: true and comment is already hidden, I am getting a warning: Comment body cannot be blank

Run marocchino/sticky-pull-request-comment@v2
  with:
    hide: true
    hide_classify: RESOLVED
    header: ***
    append: false
    recreate: false
    delete: false
    only_create: false
    only_update: false
    hide_details: false
    hide_and_recreate: false
    ignore_empty: false
    skip_unchanged: false
    follow_symbolic_links: false
    GITHUB_TOKEN: ***
  env:
    URL: https://api.github.com/repos/***/issues/564/comments
Warning: Comment body cannot be blank

Warning doesn't show up when a comment is not hidden yet.

In my case, the comment isn't hidden at run time, I get the warning, and it doesn't get hidden by the end of the action run. It seems that hide: true as documented in the readme is broken:

I'm using

      - if: steps.stats.outputs.changes <= 1000
        uses: marocchino/sticky-pull-request-comment@v2
        with:
          header: lockfile # Unique identifier for the comment
          hide: true
      - if: steps.stats.outputs.changes > 1000
        uses: marocchino/sticky-pull-request-comment@v2
        with:
          header: lockfile # Unique identifier for the comment
          recreate: true
