Empty lines when using paths match front page

Problem/Motivation

Trying to limit a field group and/or fields to two or more specific paths, the field group was also showing when I edit the home page (but not other nodes0

Steps to reproduce

When listing more than one allowed path to match (with "any of these"), include a blank line at the end of the list. Field group and/or fields will display on those paths and on the home page.

Proposed resolution

Ignore newlines in path configuration. Would need some way to indiciate the homepage path or '/', is "" still a thing?
