Include Paths can't go back one level folder

[ns-bruno]

I am currently using the following configuration in vscode's settings.json file:

{
    "harbour.compilerExecutable": "..\\compiler\\xharbour\\bin\\harbour.exe",
    "harbour.extraOptions": "..\\Compiler\\xharbour\\include",
    "harbour.extraIncludePaths": [
        "..\\Compiler\\fwh_2002\\include",
        "..\\Compiler\\xharbour\\include"
    ],
}

I realized that the function resolvePredefinedVariables(v) cannot go back one level of the current project folder (Workspace Folder) using ..\\ as you can see in the example of settings.json above.

So it would be interesting and of great help implement the resolvePredefinedVariables (v) to accept back level using ..\\.
