    You probably are looking for a different event than keyup. input works best for what you are trying to do imo.

    $(function() {
    $('#cstedit-addembossing').on("input", function() {
        this.value = this.value.toUpperCase();
    });
});

    // those listeners are added by customizer-final-v33.js
foo.addEventListener('change', e => display.textContent = foo.value);
foo.addEventListener('input', e => display.textContent = foo.value);

// this is basically your listener
foo.addEventListener('keyup', e => foo.value = foo.value.toUpperCase());
    <textarea id="foo"></textarea>
<hr />
<h1 id="display">Type and texarea will update this text.</h1>

    To fix that, here you go:

    // those listeners are added by customizer-final-v33.js
foo.addEventListener('change', e => display.textContent = foo.value);
foo.addEventListener('input', e => display.textContent = foo.value);

// this is basically a working version your listener
foo.addEventListener('keydown', (e) => {
  event.preventDefault();
  foo.value = foo.value + String.fromCharCode(e.keyCode).toUpperCase();
  foo.dispatchEvent(new CustomEvent('input', { bubbles: true }));
})
    <textarea id="foo"></textarea>
<hr />
<h1 id="display">Type and texarea will update this text.</h1>
