The following won't render: ``` library(plotly) plot_ly( labels = c("Seth", "Enos", "Noam", "Awan", "Enoch"), parents = c("", "Seth", "Seth", "", "Awan"), values = c(12, 10, 2, 4, 4), type = "sunburst", branchvalues = "total" ) ``` Once we add a "root" the plot renders fine: ``` library(plotly) plot_ly( labels = c("Eve", "Seth", "Enos", "Noam", "Awan", "Enoch"), parents = c("", "Eve", "Seth", "Seth", "Eve", "Awan"), values = c(16, 12, 10, 2, 4, 4), type = "sunburst", branchvalues = "total" ) ```  I guess, but I'm not sure if [this pull request](https://github.com/plotly/plotly.js/pull/4253) already adresses the problem. I saw the problem [here](https://community.plot.ly/t/plotly-sunburst-returning-empty-chart-with-branchvalues-total/26582) first.
