Unchanged files with check annotations (beta)

[VictorComette]

Describe a bug

I'm unable to prevent coverage annotation on unchanged files. I've setup the action with annotations: coverage and expected to have annotations to changed files only, as stated in the docs:

coverage - Will annotate those sections of your code that test did not cover. Limited to changed lines when used on a Pull Request

Even so, GH is adding a entire section on the diff entitled "Unchanged files with check annotations (beta)" with a bunch of annotations.

As we are starting a long effort of covering a huge legacy application with tests, this is becoming an issue due to the extensive number of files without coverage.

I see this should be addressed already, per this closed issue, but it's not working for me.

Expected behavior

To have coverage annotations on changed files only (changed lines if possible).
