Missing underscore library

Problem/Motivation

After upgrading to Drupal 9.4.1 and Geofield Map 8.x-2.82, pages that used to have maps were no longer showing maps.
The following js error was evident:
"Uncaught ReferenceError: _ is not defined at geofield_map_gmap_formatter.js 115:9".
Upon investigation I discovered that underscore.js was loading when logged in as admin, but not when using the page as anonymous user.

Steps to reproduce

On a site with core 9.4.1 and Geofield Map 8.x-2.82, insert a View with format "Geofield Google Map" that displays content with geo locations. The map will not show when the user is not logged.

Proposed resolution

It appears that Drupal Core does not load underscore.js for anonymous users. This issue can be remediated by adding a dependency on core/underscore in geofield_map.libraries.yml. For example:

geofield_google_map:
  ~
  dependencies:
      - core/jquery
      - core/once
      - core/drupal
      - core/drupalSettings
      - core/underscore
