Schemas not loaded in github.dev (hosted vscode)

Describe the bug

Schemas configured via a .vscode/settings.json don't load in github.dev

Expected Behavior

Schemas work like in local vscode

Current Behavior

I get an error:

Unable to load schema from '/schema/workflows.schema.json': No content.

Steps to Reproduce

• Create a JSON schema file (eg in /schema.json)
• Add a .vscode/settings.json file with the following contents

{
  "yaml.schemas": {
    "schema.json": [
      "foo.yaml"
    ]
  }
}

• edit foo.yaml

Environment

• Windows
• Mac
• Linux
• other: github.dev

Reproduce the issue in github.dev using the root schema.json, .vscode/settings.json, and foo.yaml described in the report. Start by comparing schema loading there with local VS Code; done means the configured schema loads for foo.yaml without the reported “No content” error.
