Chart width error with shiny tabpanels

Hello,

When a plot is loading and at that moment you changes the tabpanel. When you return to the initial tab panel the width of the graph is incorrect.

We have tried all kinds of solutions such as putting the plots inside a column. But nothing works to fix the problem.

Using the following code, when starting the application and you changes to "Hello 2" before the graph of "Hello 1" has been rendered. The graph of "Hello 1" looks like in the following image

and not as in "Hello 2"

library(shiny)

`ui <- fluidPage(
selectInput("choice", "Choose", choices = names(iris), selected = NULL),
tabsetPanel(id="tabset",
tabPanel("Hello 1",value = "C1",
plotlyOutput("case1")),
tabPanel("Hello 2",value = "C2",
plotlyOutput("case2")) ))

server <- function(input, output) {

output$case1 <- renderPlotly({
    Sys.sleep(5)
    plot_ly(iris, x = ~get(input$choice), y = ~Sepal.Length, type = 'scatter', mode = 'markers')
})

output$case2 <- renderPlotly({
    Sys.sleep(5)
    plot_ly(iris, x = ~get(input$choice), y = ~Sepal.Length, type = 'scatter', mode = 'markers')
})

}

shinyApp(ui = ui, server = server)
`

Thanks.

付属の最小限の Shiny アプリから始め、renderPlotly が完了する前に tabsetPanel のタブを切り替えて問題を再現します。タブが再び表示されたときに plotlyOutput のサイズがどのように処理されるかを追跡します。完了条件は、最初のタブに戻った後に両方のプロットが正しい幅を再取得し、遅延レンダリングのシーケンスに対する回帰テストがあることです。
