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.

从提供的最小 Shiny 应用开始，在 renderPlotly 完成之前切换 tabsetPanel 的标签页来复现问题。跟踪标签页再次可见时如何处理 plotlyOutput 的尺寸；完成标准是返回初始标签页后两个图都恢复正确宽度，并为延迟渲染序列添加回归测试。
