Hover information partially disappear when providing color input

[AlexisDerumigny]

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")
