Individual marker styling inconsistent

Hi, thank you for making and working on such a wonderful plotting package.

For one of the projects I'm working on, I'm trying to style individual markers, however it's inconsistent when trying to target individual markers. For example I want to make the fourth point as full opacity (1) and larger (15) while the others are at 0.2 and size 10. I would expect "sample4" to be at full opacity, but it's "sample3". Am I doing something wrong?

test_data <- data.frame(
    x_data = c(2.8113, 5.8112, 7.3461, 15.5405, 16.3035),
    y_data = c(2, 2, 2, 6, 3),
    groups = c("group1", "group1", "group2", "group2", "group1"),
    samples = c("sample1", "sample2", "sample3", "sample4", "sample5")
)
plotly::plot_ly(
    test_data,
    x = ~x_data,
    y = ~y_data,
    mode = "markers",
    type = "scatter",
    color = ~groups,
    text = ~samples,
    marker = list(
        size = c(10, 10, 10, 15, 10),
        opacity = c(0.2, 0.2, 0.2, 1, 0.2)
      )
    )

produces the following plot

Thanks a lot in advance!

Reproduisez l’exemple plot_ly fourni dans le dépôt plotly.R et examinez comment les vecteurs marker groupés sont associés aux points tracés. Comparez le style marker affiché avec les vecteurs size et opacity demandés. Le travail est terminé lorsque sample4 reçoit size 15 et opacity 1, tandis que les autres échantillons reçoivent size 10 et opacity 0.2.
