Deferring cookiesjsr.conf library blocks loading of the cookies consent block

Problem/Motivation

After upgrading from 1.2.12 to 1.2.16 on Drupal 10.5.1 and visiting the site, I noticed the Cookie Consent block was not appearing. Upon inspecting the page, the browser console tells me there is a file within cookiesjsr library that is not found (despite being there from the beginning). It is a translation json, so it may not apply to people who do not have alternative locales.

Steps to reproduce

On Drupal 10.5.1 upgrade to any version up from 1.2.12 and check by visiting different locales on the same page.

Proposed resolution

When not deferring this library, it works. Patch attached for v1.2.16.

Remaining tasks

Review if this is widespread problem or needs a different solution or consideration.
