find references not working in code-oss

[FTomaYoamb]

When trying to "Find References" for a symbol, even if I see some results in the verbose messages, vs code displays this warning : "[ms-vscode.references-view]: Proposed API is only available when running out of dev or with the following command line switch: --enable-proposed-api ms-vscode.references-view". Running the specified command line doesn't make any difference.
