Does this issue occur when all extensions are disabled?: No

• VS Code Version: 1.71.0
• OS Version: macOS 12.15.1

Steps to Reproduce:

1. Define any npm task that is in a subfolder using the "path" property, and define a problemMatcher that uses "fileLocation": "relative".
2. It won't work, as the directory that it should be relative to will be the ${workspaceFolder} rather than the actual working directory of the npm script set by "path".
