Multiple language-specific editor settings does not work in workspace-specific settings

[macintacos]

Type: Bug

The following setting is valid in my own user settings.json file:

    "[typescript][yaml][markdown]": {
        "editor.defaultFormatter": "esbenp.prettier-vscode"
    }

If I place that in a project's .vscode/settings.json file, it does not work as expected. It only works if you specify a single language.

The documentation does not call this out as a limitation of workspace settings, so I can only assume that this is a bug.

Can you please share all your user settings and workspace settings?
