Bug: chartjs-plugin-datalabels throws Cannot read properties of null (reading 'x') on pie/doughnut charts in Filament

[NikFarees]

Bug: chartjs-plugin-datalabels crashes on pie / doughnut charts with Cannot read properties of null (reading 'x')

Summary

When using chartjs-plugin-datalabels in a Filament ChartWidget, line and bar charts work as expected, but pie and doughnut charts throw a runtime error in the browser console.

The chart still renders in some cases, but the plugin crashes during draw / hover lifecycle.
