Upon further investigation it was found out that duplication is only announced for elements only with screen reader NVDA (Voice over announces correctly one time). And it was checked on the websites where elements are really working (coded) correctly, also for Elastic UI elements in Figma.
In conclusion: it is related with NVDA, not with the implementation of the element. Due to this, closing this and similar issues reported as they do not need fixing.
