In VS Code rulers are not drawn for Haskell files

Question

I have added vertical rulers to VS Code in the settings.json file like this:

    "editor.rulers": [
        40,80],

This works, e.g. for Python files but strangely not for Haskell files. (I am using the usual Python and Haskell extensions.)

Here a screenshot of VS Code with Haskell files:

Any idea how I can make the rulers visible for Haskell as well?

@lsmor Yes, I have rulers at 40 and 80 cols - just to make testing of the rulers easier. — halloleo, Apr 07 '23 at 02:13
Whatever it is is not related with the haskell extension. rulers is a vscode thing independent from the extension. Are you sure your _global_ setting uses rulers? or you use rules in local settings in your python — lsmor, Apr 07 '23 at 08:30

I could not find any rulers setting in any of the normal settings files. However, in my current project.code-workspace file I had the lines:

        "settings": {
                "editor.rulers": []
        }

which overwrote the ruler preferences in the settings files!

When I took these lines out of the workspace file everything went back to normal and the ruler appeared as expected

Note: Because the settings were stored in the workspace file, other projects (like my python projects with other or no workspace file) were not affected. -- So it appeared to me that the issue is Haskell-related, but infact it was only related to my Haskell workspace file.
