Login UI weird on mobile

I’ve noticed some weird behavior on the SCALE login screen using Chrome for Android. If I let the login page load and just tap the username field, it does not bring up the saved password option. However, if I scroll the page slightly after it loads, tapping the username field does bring up the saved password prompt. I’ve never seen this on any other site, but it’s always reproducible for me with TrueNAS and CfA. I can’t remember if it was like this under Bluefin (I was only on Bluefin for a short amount of time before Cobia released), but it has been consistent on both Cobia and Dragonfish.

(I think I’ve seen this once or twice on the desktop version of Chrome as well, but I can’t remember for sure as I use my tablet much more than I use my desktop.)
