Whenever I add UserProperties programmatically using PropertiesService.getUserProperties().setProperty(key,value), the properties do not show up in the Script Editor's GUI under File > Project Properties > User Properties. If I add the User Properties manually and click "save," the properties show up.

Code:

// Add a user property programmatically
function addUserProperty() {
  PropertiesService.getUserProperties().setProperty("hello", "world");
}

// A workaround to view user properties without the buggy GUI
function viewUserPropteries() {
  if (PropertiesService.getUserProperties().getKeys().length == 0) Logger.log("No user properties were found");
  var userPropertyKeys = PropertiesService.getUserProperties().getKeys();
  for (var i in userPropertyKeys)
    Logger.log(userPropertyKeys[i] + ": " +   PropertiesService.getUserProperties().getProperty(userPropertyKeys[i]));
}

What steps will reproduce the problem?
1. Run the addUserProperty function.
2. Go to File > Script Properties > User Properties to verify that User Properties don't show up.
3. Fun the viewUserProperties function.
4. Go to View > Logs to see that User Property was actually added.
