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
#> 10 10 10            T pentagon           2

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")))

从 issue #1155 中可复现的 R 示例开始，追踪标记符号和标记线值如何传递到渲染路径。完成的标准是点 (3, 3) 渲染为没有线的圆，而五边形点保留其红线。
