Hi Rafael,
You can remove the keydown event for dropdown button’s popup in the ‘created’ event to resolve your issue. Please refer the below code snippets and sample link.
dropdownCreated() {
let dropdownPopup: Element = document.getElementById('dropdownbutton' + '-popup'); // drop button id+ '-popup'
dropdownPopup.removeEventListener('keydown', (dropdownPopup as any).eventListeners()[1]);
