Mouseover "help text" not showing in 8.5

After a clean install of 8.5 including adding 7.x customization, the field “help” text does not show on mouseover. The help text is showing in the field edit but not on mouseover when creating a new account, contact, or opportunity. Any suggestions?

It seems, someone is already working on that issue:

Hopefully it’ll be included in the next maintenance release.

If my memory serves me correctly, This works for users but not for admin. If you’re logged in as admin you wont see it. At least that’s how I remember it working in 7.

Thank you for the quick and helpful response. I appreciate that.
