enable zooming of any rectangular shape on a Plotly heatmap

Currently there are 2 “zooming” behaviours in Plotly.JS heatmaps:

• Demo here : Here you can take any rectangular shape for the zoom (click, drag and drop). But then the pixels are not square, which is not ok for some applications (the aspect ratio is not preserved, and sometimes it should be preserved):

• Demo here : Here the pixels are square thanks to {'yaxis': {'scaleanchor': 'x'}}, but then you can zoom only with a certain aspect ratio rectangular shape, which is sometimes a limiting factor for the UX/UI:

But often, it is useful to have both, i.e. being able to draw a rectangle selection zoom of any shape + keep square-shape pixels.

IMHO this feature should be available directly in Plotly heatmaps (because it's the standard expected behaviour, which is common in Matplotlib etc.), what do you think? @lvlte @archmoj

まず、リンクされた2つのヒートマップデモを再現し、リンクされた Stack Overflow の解決策を読む。そのズームとアスペクト比の挙動を比較し、次に提案されたインタラクションが Plotly heatmaps にどう適合すべきかを判断する。完了の条件は、任意の矩形ズームで正方形のピクセルが維持され、適切なテストでカバーされていること。
