I've tagged the appropriate team on that Github issue, you should get a response soon. I wasn't able to reproduce this, but I don't have as much data in my cluster as you. One recommendation would be to try disabling Chrome extensions (or using an incognito window) to see if there may be something interfering.
I just tried with Incognito mode and I got the same behaviour.
It should be related to the way the UI is trying to detect the panel maximum height (also noticed the scroll bar) to decide whether to display 3 dots or truncated host details.
