JSON schema preferences

We are using the extension @theia/json but currently having troubles using a local schema located in the theia runtime workspace.
The definition of ‘json.schemas : url’ says it accepts a relative path to a schema in the current directory.
(https://github.com/eclipse-theia/theia/blob/master/packages/json/src/browser/json-preferences.ts)
When using a relative path I get 'Error: ENOENT: no such file or directory, open ‘/.schemas/myjsonschema.json’ '.
If I use the absolute path to the schema (e.g. via the workspace settings) it works. Is this intended?
Thanks for your answer in advance.

No, i don’t think it is intended. Is it possible to reproduce with Theia repo. Could you open an issue please?
