Accessibility Regression: SelectButton roles (radio & checkbox)

[c-o-l-i-n]

Describe the bug

In v17, the buttons in a single-selection SelectButton have role="radio", and the buttons in a multiple-selection SelectButton have role="checkbox". And when the buttons are selected, they have aria-checked="true".

However, in v18 and v19, the buttons have the implicit role button. And instead of aria-checked="true", they have aria-pressed="true".

Using the radio and checkbox roles makes sense because the user selects options like they would with a set of radio buttons or checkboxes.

v17: https://v17.primeng.org/selectbutton

v19: https://primeng.org/selectbutton

Steps to reproduce the behavior

Use the SelectButton component in PrimeNG v18 or v19.

Expected behavior

The buttons in a single-selection SelectButton component use role="radio" with aria-checked="true", and the buttons in a multiple-selection SelectButton component use role="checkbox" with aria-checked="true".
