the chart's screen-reader table wore srOnly directly; overflow and height do not apply to a table box, so it laid out 1200px tall below the page while clip-path hid the paint. wrap it in a hidden div, which clips properly and keeps the table role. failure detail is the diagnostics page's job since milestone 27; the column and the now dead formatAge go.
