make Scatter_polar interactive selection consistent with the non-polar scatter plot

When using Box Select or Lasso Select from the Modebar for the scatter_polar charts, the selection is not editable nor draggable as in regular scatter charts. This can be easily verified by interacting with the charts from the official Plotly website:

1. Scatter Polar (not editable or draggable)
2. Scatter

We should expect the same behavior across all charts available in Plotly.

まず、issue にリンクされている公式の Scatter Polar と Scatter の例を、Modebar の Box Select と Lasso Select を使って比較します。scatter_polar と通常の Scatter の選択動作を追跡し、その後、利用可能なすべてのチャートで polar の選択範囲を同じ方法で編集およびドラッグできることを確認します。
