As of 3.57.0 (or some earlier version) the use of <td role="button> does not meet a11y guidelines and shows a warning.
This effects the expand/collapse button, since the current behaviour treats the cell as a button. This assignment of role="button" is needed for tabindex="0" the attribute which allows tabbing through the expand collapse buttons.
Instead of using the tabindex on the td, use a nested span
