I have mainly used Chrome and Safari, and I haven't seen this issue come up before. I did just deploy a new update that will (hopefully) prevent a page refresh from happening when there are unsaved changes, and I also implemented a sticky footer for the Update Pack button so it’s always visible on the screen.
Let me know how this works out for you, and feel free to send a screen recording if you are experiencing any unusual behavior.
