Marker symbol and line rendered in wrong order

Given the code below, Plotly render the marker symbols and lines in wrong order. From df, you can see the point (3, 3) should be a circle without line. But it's rendered as a pentagon with the red circle:

library(plotly)
#> Loading required package: ggplot2
#> 
#> Attaching package: 'plotly'
#> The following object is masked from 'package:ggplot2':
#> 
#>     last_plot
#> The following object is masked from 'package:stats':
#> 
#>     filter
#> The following object is masked from 'package:graphics':

#>     layout

df <- data.frame(x = seq(1, 10), y = seq(1, 10),
                 Sample_Group = rep(c("N", "T"), 5),
                 Symbol = rep(c("circle", "pentagon"), 5))
df$Symbol_Line <- sapply(df$Symbol, function(x) {ifelse(x == "pentagon", 2, 0)})
df
#>     x  y Sample_Group   Symbol Symbol_Line
#> 1   1  1            N   circle           0
#> 2   2  2            T pentagon           2
#> 3   3  3            N   circle           0
#> 4   4  4            T pentagon           2
#> 5   5  5            N   circle           0
#> 6   6  6            T pentagon           2
#> 7   7  7            N   circle           0
#> 8   8  8            T pentagon           2
#> 9   9  9            N   circle           0

p <- plot_ly(df, x = ~x, y = ~y,
             type = "scatter", mode = "markers",
             color = ~Sample_Group,
             marker = list(symbol = ~Symbol,
                           size = 15,
                           line = list(width = ~Symbol_Line,
                                       color = "red")))

issue #1155 の再現可能な R の例から始め、マーカーシンボルとマーカーラインの値がどのようにレンダリングパスへ渡されるかを追跡します。完了の条件は、点 (3, 3) が線なしの円としてレンダリングされ、五角形の点は赤い線を維持することです。
