Sorry if this has already been raised, but I didn't see it. When loading / refreshing the Admin UI in 8.5.1, it briefly but *visibly* shows a placeholder for the "SolrCore Initialization Failures" error message, with a lot of redness. It looks like there is a real problem. Obviously the message then disappears, and it can be ignored. However, if I was a first time user, it would not give me confidence that everything is okay. In a way, an error message that appears briefly then disappears before I can finish reading it is worse than one which just stays there.
Here's a screenshot of what I mean https://drive.google.com/open?id=1eK4HNprEuEua08_UwtEoDQuRwFgqbGjU and a gif: https://drive.google.com/open?id=1Rw3z03MzAqFpfZFU4uVv4G158vk66QVx I assume that this is connected to the UI updates discussed in https://issues.apache.org/jira/browse/SOLR-14359 Cheers, Colvin
