VSCode: In a multi-root workspace, Qt Qml extension fails to resolve the "workspaceFolder" setting correctly

AnttiK

Hi all,

I have a VS Code multi-root workspace project located in https://github.com/anttikes/usb-fm-radio/. When I open the workspace file in the root, go to "GUI" and open "Main.qml" I get an error from the qmllint tool that the "GUI" module could not be found.

The reason seems clear: a missing import path. I then modify ".vscode/settings.json", and add the string array setting "qt-qml.qmlls.additionalImportPaths" to look like this:

"qt-qml.qmlls.additionalImportPaths": [
    "${workspaceFolder}/build/GUI/components"
]

This causes a rather perplexing behavior. In Main.qml the import path error stays and a new directory entry appears into the list, but the path looks wrong:

For some reason, the extension or the linter has reviewed the workspace file and taken the first entry in the "folders" sub-key. This behavior is obviously wrong because we are in the "GUI" portion of the multi-root workspace.

Here is an excerpt of the "qt-qml" output in VS Code, with my username redacted from the output:

Thanks. Can I somehow login to this different site with the same account I have here? It doesn't seem to accept my current credentials...
