QLocale::uiLanguages() returns english language if run from Finder

 Qt APIs(QLocale::system().uiLanguages(), QLocale::system().name()) are returning locale differently based on the way the application is launched.

• If the application is launched from Finder, locale returns English as preferred even when preferred is set to Japanese in system settings
• If application is launched from Terminal, locale returns properly and it's as per the preferred language set in system settings

  int main(int argc, char *argv[])
  {
      QApplication a(argc, argv);
      QLocale qLocale = QLocale::system();
      QStringList uiLanguages = qLocale.uiLanguages();
      qDebug()<<uiLanguages;
    
      return a.exec();
  }

  Steps,

• Change the System Preferred Language to Japanese and Region to Japan.
• Just make sure there is only one preferred Language i.e. Japanese.
• restart machine.
• Then run above code 

Expectation is that it should return an array with languages and first should be Japanese.

("ja-JP", "ja", "ja-Jpan-JP", "en-JP", "en", "en-US", "en-Latn-US")
But result of qLocale.uiLanguages() is "en", "en-US", "en-Latn-US", "ja-JP", "ja", "ja-Jpan-JP"

Looks like similar bug fixed in past:
