Highcharts Dashboards / Grid Pro: `DataTable.setCell` and column writers treat `__proto__` as an existing column.

Impact When a single cell value is written to a data table, the column id is used as a key on the table's column collection without filtering, so a column id of proto resolves to Object.prototype, is taken for an existing column, and the write lands at the row index on Object.prototype; a column ...
