🐛 Monorepo configuration seems incompatible since v1.8.1

[manakuro]

IDE and version

WebStorm 2025.2

Extension version

1.10.0

Biome version

1.9.4

Operating system

• Windows
• macOS
• Linux

Description

Since v1.8.1, I've encountered some difficulties getting the plugin to function properly in monorepo configurations. I was able to verify that it works as expected when manually downgrading to v1.7.2.

Steps to reproduce

1. Clone the following repository locally: https://github.com/manakuro/biome-report-issue
2. Open the repository in WebStorm.
3. After opening, install the npm packages with the following command: pnpm install
4. After installing the npm packages, open files like apps/web/app/page.tsx, make some edits, and check if Biome is working.

Expected behavior

The plugin should work seamlessly in monorepo environments, detecting and applying Biome configuration files at the appropriate workspace levels, just as it did in v1.7.2.

Does this issue occur when using the CLI directly?

No
