Hover information partially disappear when providing color input

Thanks for this package, it is very useful!
When using it, I encountered a kind of weird bug.

The two following plots should be identical and behave in the same way, except that the second one has colored points.

library(plotly)

plot_ly() %>%
  add_markers(
    x = c(1,2,3), y = c(1,2,3), z = c(1,2,3))

plot_ly() %>%
  add_markers(
    x = c(1,2,3), y = c(1,2,3), z = c(1,2,3), color = c(1,2,3))

For the first plot, all the values appear when I hover over all 3 points, as expected.
However, for the second plot, I can only hover over the second point; no information appears when I hover over the first nor the third point. Here are two screenshots that I made with the second plot (the one that has the bug).

The expected behavior is that the similar type of information would appear for all points.

More generally, I have the impression than when doing a scatter plot with $n$ points, I can only get the hover information of $n-2$ of them if they are colored. For example, the hoverinfo do not appear for the "extreme" points of this plot:

n = 10
plot_ly() %>%
  add_trace(
    x = 1:n, y = 1:n, z = 1:n, color = 1:n, type="scatter3d", mode="markers")

首先运行两个 plot_ly()/add_markers() 示例以及 n = 10 的 scatter3d 示例，以复现极值点处缺失悬停信息的问题。比较有颜色和无颜色点的悬停行为；当每个点都能一致地显示悬停信息时即表示完成。
