bug with selectedpoints when using multiple histogram

Hi,

I found a bug while trying to select a bar in a diagram with multiple histograms. I reproduce the issue on this codepen: https://codepen.io/martin-alfonsi/pen/ZEJwxNz

It seems that if all the values from an histogram are before all the values from the other histogram, then trying to select a bar on the furthest histogram using selectedpoints will deselect all instead.
Here the blue 1.5 bar should be select but all bars are unselected:

And if I move the orange bar (line 7 from the JS) between or after the blue, then there is no issue:

从链接的 CodePen 复现开始，跟踪 plotly.js 对多个直方图和 selectedpoints 的直方图选择处理。复现一个直方图的值全部排在另一个直方图的值之前的情况，然后将其与正常工作的重新排序情况进行比较。完成的标准是：选择最远的直方图柱时，该柱仍保持选中，而不是取消选择所有柱，并且针对所报告排列方式具有回归测试覆盖。
