Fixes #16637.
We missed adding the relationship of
helperText
with some specific element.This PR adds
aria-describedby
to the rootspinbutton
group
element and also addsaria-live="polite"
to signal that this element changes need to be read by the screen reader.On the "v6" (input) approach, it is not needed because the
aria-describedby
is added on theinput
element, which is focused and receiving changes.P.S. This is technically a small regression due to it working fine on the old "INPUT" approach. 🙈
