I've written some code with the aim of being able to automatically add journal abbreviation tags when creating a new entry to make it easier for me to filter for specific journals.
My code works fine in the following scenario:

1. Adding DOIs manually.
2. When importing a PDF.
   However, once I disengage from the Zotero software and add an entry via the zotero connector in Safari, I find that the journal's tags successfully appear automatically, but are then automatically removed!
   Why is this?

/**
 * add publicationTitle tags
 */
const Zotero = require("Zotero");

(async function () {
    // Check if the trigger is created by a single item
    if (!item) {
        return; // No target item provided, return directly
    }

    // Define a mapping from publicationTitle to abbreviation (case insensitive)
    const titleToAbbreviation = {
