Category-wise script execution order anomaly

Problem/Motivation

I am using the Opt-in with categories mode and have two categories. Each category is associated with a Javascript file in the "Disable the following JavaScripts when consent isn't given" section. Within the EU cookie banner, if I select the first category, click "Save preferences", then select the second category, and then click "Save preferences" again then all is fine; both Javascript files load as expected. But if I select the second category first, click "Save preferences", then select the first category, and finally click "Save preferences" again then only the Javascript file for the second category loads.

Steps to reproduce

Banner setup

1. Select Opt-in with categories as the consent method.
2. Add two categories with the following machine names: first_category, second_category.
3. Create two Javascript files called first-category-script.js and second-category-script.js. Place these inside the sites/default/files/js/ directory. A simple debug statement should suffice as their content. Sample contents for the first and second script given below.
4. Add this in the "Disable the following JavaScripts when consent isn't given" section:
   

   first_category:public://js/first-category-script.js
   second_category:public://js/second-category-script.js

5. Select the "Enable floating privacy settings tab and withdraw consent banner" and "Put the "Withdraw consent" button on the cookie information banner." options in the WITHDRAW CONSENT section.

Alternatively, import the given config from /admin/config/development/configuration/single/import. Choose "Simple configuration" as the Configuration type and "eu_cookie_compliance.settings" as the Configuration name in the import form.

Interaction

1. Open the homepage.
2. The Cookie banner should reveal itself.
3. Select the "Second category" and click the "Save preferences" button. The debug output from sites/default/files/js/second-category-script.js should appear in the Javascript console.
4. Select the "First category" and click the "Save preferences" button. The expected Javascript console output is the debug string from sites/default/files/js/first-category-script.js. But instead the debug string from sites/default/files/js/second-category-script.js gets repeated. This is the bug.
