1. Add some CT logs in System Configuration -> Certificate Transparency Logs.
2. Load the CT log page again (e.g. by pressing it's tab)
3. Order of logs is changed
(it's possible that the order does not change by luck, so you may need to try it several times, with different URLs)
To prevent future regressions, I've changed the type of all variables/parameters containing CT logs from Map/Set to LinkedHashMap/LinkedHashSet
