When bookmarking, add option to NOT retain all the verbose plotly parameters

When I have a plotly plot in a bookmarkable shiny app, the bookmarking URL becomes very long and messy with lots of plotly-related data that doesn't seem too useful. It would be nice if there was an easy way to turn that off, or perhaps even just not include all this information by default.

Example app:

library(shiny)
library(plotly)

ui <- function(req) {
  fluidPage(
    bookmarkButton(),
    plotlyOutput("plot")
  )
}

server <- function(input, output, session) {
  output$plot <- renderPlotly({
    plot_ly(economics, x = ~pop)
  })
}

shinyApp(ui, server, enableBookmarking = "url", options = list(port = 3900))

When I just open this app and click on the bookmark button, I get this URL:

http://127.0.0.1:3900/?_inputs_&.clientValue-default-plotlyCrosstalkOpts=%7B%22on%22%3A%22plotly_click%22%2C%22persistent%22%3Afalse%2C%22dynamic%22%3Afalse%2C%22selectize%22%3Afalse%2C%22opacityDim%22%3A0.2%2C%22selected%22%3A%7B%22opacity%22%3A1%7D%2C%22debounce%22%3A0%2C%22color%22%3A%5B%5D%7D&.clientValue-plotly_relayout-A=%22%7B%5C%22width%5C%22%3A1570%2C%5C%22height%5C%22%3A400%7D%22

looks unnecessarily long. If I interact with this basic plot a little bit, I get an even longer URL such as

http://127.0.0.1:3900/?_inputs_&.clientValue-default-plotlyCrosstalkOpts=%7B%22on%22%3A%22plotly_click%22%2C%22persistent%22%3Afalse%2C%22dynamic%22%3Afalse%2C%22selectize%22%3Afalse%2C%22opacityDim%22%3A0.2%2C%22selected%22%3A%7B%22opacity%22%3A1%7D%2C%22debounce%22%3A0%2C%22color%22%3A%5B%5D%2C%22persistentShift%22%3Afalse%7D&.clientValue-plotly_hover-A=null&.clientValue-plotly_relayout-A=%22%7B%5C%22dragmode%5C%22%3A%5C%22lasso%5C%22%7D%22&.clientValue-plotly_selected-A=%22%5B%7B%5C%22curveNumber%5C%22%3A0%2C%5C%22x%5C%22%3A294999.5%2C%5C%22y%5C%22%3A43%7D%2C%7B%5C%22curveNumber%5C%22%3A0%2C%5C%22x%5C%22%3A304999.5%2C%5C%22y%5C%22%3A46%7D%5D%22

But even though it's so long, pasting this back into the URL bar goes back to the default plotly view and it did not retain the interactions I did. So it doesn't seem too useful to have the bookmark URL dirtied for this.

I'm not sure if this is a plotly issue, a crosstalk issue, an htmlwidgets issue, or maybe even a shiny issue. If this is the wrong place to post, let me know where it should go instead.

首先复现带有 URL 书签功能的示例 Shiny 应用，并比较 Plotly 交互前后的生成 URL。调查书签 URL 如何捕获报告中所述的 plotly 相关参数；如果存在一种实用方式，可以默认或通过选项省略这些参数，同时不破坏有用的书签行为，则视为完成。
