🐛 `editor.formatOnSave` only works if set in language-specific configuration blocks

VS Code version

1.95.0-insider

Extension version

v2024.10.131712 (pre-release)

Biome version

1.9.3

Operating system

[ ] Windows
[X] macOS
[ ] Linux

Description

The following configuration, setting biome as a project-wide formatted, won’t work.

{
  "editor.formatOnSave": true,
  "editor.formatOnSaveMode": "file",
  "biome.enabled": true,
  "editor.defaultFormatter": "biomejs.biome"
}

If set on a per-language basis, Biome will actually start formatting files automatically.

(Example)

{
  "editor.formatOnSave": true,
  "editor.formatOnSaveMode": "file",
  "biome.enabled": true,
  "[typescriptreact]": {
    "editor.defaultFormatter": "biomejs.biome"
  },
  "[typescript]": {
    "editor.defaultFormatter": "biomejs.biome"
  },
}

Steps to reproduce

{
  "editor.formatOnSave": true,
  "editor.formatOnSaveMode": "file",
  "biome.enabled": true,
  "editor.defaultFormatter": "biomejs.biome"
}

Expected behavior

Should automatically format files when configured to do so.

Does this issue occur when using the CLI directly?
