Description of problem:

In the new PF5 Settings page, when I fill a value of "Empty", it shows absolutely the same as when the field is actually empty, i.e. contains nothing. This is confusing and it was better in the original page.

How reproducible:

Deterministic

Is this issue a regression from an earlier version:

Yes

Steps to Reproduce:

1. Have a Satellite with PF5 Settings

2. Administer -> Settings

3. Fill in "Instance title" = "Empty" and confirm

Actual behavior:
The empty field is indistinguishable from "Empty" field

Expected behavior:
In the previous version, empty fields were in grey
