formatter: config not found when using vs workspaces

[Miodec]

(This is not an issue if the config path is not specified)

When trying to set a config file for the formatter when using a workspace, oxfmt is reverting to default config (file is located in workspace root):

{
  "folders": [
    {
      "name": "root",
      "path": "./",
    },
    {
      "name": "backend",
      "path": "backend",
    },
    {
      "name": "frontend",
      "path": "frontend",
    },
    {
      "name": "packages",
      "path": "packages",
    },
  ],
...
"oxc.fmt.configPath": ".oxfmtrc.json",
...
