can't access Resources/ inside main()

I have an app that needs to do some things (like decide whether to decorate the window) before the app is run. This needs to be configured by a file inside the Resources/ folder. Usually the solution is to add ofSetDataPathRoot("../Resources"); but that doesn't work inside main():

#include "ofMain.h"
int main() {
    ofSetDataPathRoot("../Resources");
    ofLog() << ofToDataPath(".", true);
}

[notice ] /Users/kyle/Documents/openFrameworks/apps/Project/App/bin/../Resources/.

I also tried adding ofRestoreWorkingDirectoryToDefault(), ofSetDataPathRoot(".") and ofToDataPath(".") before ofSetDataPathRoot().

The only solution I found is to imitate the code inside defaultDataPath():

ofSetDataPathRoot(ofFilePath::join(ofFilePath::getCurrentExeDir(), "../Resources"));

Start by tracing ofSetDataPathRoot(), ofToDataPath(), and defaultDataPath(), then compare their behavior when called from main(). Inspect the existing ofFilePath::getCurrentExeDir() workaround and verify the expected Resources/ path on macOS; done means the documented call works inside main() without manually reproducing defaultDataPath().
