Accessibility: nested-interactive violation from focusable controls inside MuiTableSortLabel

[ciiay]

Context

Axe-core reports nested-interactive (serious) on tables rendered via @material-table/core when column sorting is enabled. In RHDH / Backstage demos this surfaces as focusable controls nested inside MuiTableSortLabel (role="button").

Problem

Interactive / focusable descendants inside the sort label create nested interactive controls, which fail axe nested-interactive and are problematic for screen reader / keyboard users.

Setting options={{ draggable: false }} reduces some nesting from drag handles, but the sort-label nesting remains an upstream markup issue.

Expected

Header / sort controls should not nest focusable interactive elements (or should use a markup pattern that passes axe nested-interactive).

Environment

• Package: @material-table/core (observed with 3.2.x in Backstage Table demos)
• Related RHDH PR: fix(theme): fix light theme a11y contrast and demo axe violations redhat-developer/rhdh-plugins#3945
• Jira: https://redhat.atlassian.net/browse/RHDHBUGS-2243

Ask

Please consider fixing the header/sort control DOM so consumers can keep axe nested-interactive enabled.

Can you add a reproduceable code example and highlight the buttons that you reference
