This is not the correct default value for the `aria-labelledby` attribute. In line 405 where it was previously assigned, `tabIndex` has value `0`. However in the `for-in` loop that follows, `tabIndex` is increased and so the generated id refers to the last tab instead of the first. The correct value for the attribute is `HtmlIds.forTab(id, 0).name()`.
