User reputation league site switcher doesn't show the selected site name

Question

In the Stack Exchange user reputation leagues page, if I select any site in the site switcher it will be set as Stack Overflow or some random site in the drop down list's selected site name.

For the Stack Overflow, Super User, Server Fault and Meta Stack Exchange, the site switcher is set to the selected site name, but the remaining do not retain the selected site name. For English Language and Usage, it changes to Physical Fitness for some reason. All the others I've tried switch to Stack Overflow.

It can be replicated in Chrome and Firefox.

In the 6 to 8 weeks this takes to get fixed, you can use the following userscript that solves the bug:

// ==UserScript==
// @name         set selected site
// @namespace    https://meta.stackexchange.com/users/158100/rene
// @version      0.1
// @description  set selected site in league
// @author       rene
// @match        https://stackexchange.com/leagues/*
// @grant        none
// ==/UserScript==

(function() {
    'use strict';

    var url = document.location.pathname.split('/');
    if (url.length >2) {
        $('.fl select option[value^="/' + url[1]+'/'+ url[2] + '/"]').prop('selected','selected');
    }
})();

It will select the correct value in the site switcher based on the current league you're looking at.

Find the source on GitHub or directly install it.
