persistent highlights do not persist in crosstalk SharedData$selection()

When using plotly with crosstalk, and highlight(..., persistent = TRUE), the selections do not synchronize as expected with SharedData$selection(). Only the last selection is selected in the SharedData object. previous ones are "forgotten". The plot highlights will be out of sync with the SharedData object.

library(tidyverse)
library(plotly)
library(crosstalk)
library(shiny)

ui <- bootstrapPage(
  wellPanel(
    plotlyOutput(outputId = "plot"),
    verbatimTextOutput(outputId = "selection")
  )
)
server <- function(input, output, session) {
  data <- mtcars %>%
    rownames_to_column("name") %>%
    SharedData$new()
  
  output$plot <- renderPlotly({
    plot_ly(data = data, x = ~disp, y = ~mpg, mode = "marker", type = "scatter") %>%
      highlight(on = "plotly_selected", off = "plotly_deselect", persistent = TRUE)
  })
  
  output$selection <- renderPrint({
    s <- data$selection()
    print(paste(sum(s), "points selected"))
  })
  
}

shinyApp(ui = ui, server = server)

plotly、crosstalk、永続的なハイライトを使用した、提供されている再現可能な R/Shiny 例を実行します。plotly で繰り返し行った選択が SharedData$selection() とどのように同期されるかを追跡し、その後、すべての永続的な選択が SharedData オブジェクトで引き続き利用可能であり、表示される件数も同期されたままであることを確認します。
