Dragmode false not working for horizontal scroll

This relates to #2844 which got partially solved by #3170 .
My problem is that dragmode = false should enable both horizontal and vertical scroll.
However, horizontal scrolling is not fully working.
In the case of a plot that is wider than the page, horizontal scrolling is not possible on a mobile device, if one tries to scroll within the axes. I want only the plot area to scroll, without the whole page overflowing the screen horizontally. That is why I arranged the divs in this way. I think this is a common use case.
Please check the following example on a mobile device:

I tried to make it as simple as possible.

まず、モバイルデバイスでCodePenの例を再現し、issues #2844 と #3170 のコンテキストと動作を比較します。dragmode=false が軸内のスクロールをどのように処理するかを追跡します。プロット領域内で横スクロールが機能し、ページ全体の横方向のオーバーフローを引き起こさず、縦スクロールも引き続き利用できれば完了です。
