Long x labels in subplot() get cut off from plot

I've created a shiny app that uses plotly::subplot(), and one of the interactive aspects of this app is that the size of the label can vary depending on user selection.

I've noticed that if there is a label that is really long (in my app the "magic number" is 55 characters, in the following reprex it is higher), that label length is ignored for sizing the plots, even with automargin = TRUE.

library(shiny)
library(plotly)
library(dplyr)
library(purrr)

#Creating dataset with 3 different sample groups, each one with 2 levels
group1 <- c("G1", "G2")
group2 <- c("Longer labels make the plot area smaller", "That's nice!")
group3 <- c("Really long labels get cut off the plot, I don't know why, that's weird", "Another label")

groups <- c("Group1", "Group2", "Group3")

df <-  as.data.frame(do.call(paste0, replicate(50, sample(LETTERS, 10, TRUE), FALSE)))

df <- df %>%
  mutate(Group1 = sample(group1, nrow(.), replace = TRUE),
         Group2 = sample(group2, nrow(.), replace = TRUE),
         Group3 = sample(group3, nrow(.), replace = TRUE),
         value = rnorm(nrow(.), 0,10))

#App
ui <- fluidPage(
  titlePanel("Testing large labels"),
  
  sidebarLayout(
    sidebarPanel(
      checkboxGroupInput("groups", "Select Groups", choices = groups, selected = groups[1])
      ),
    
    mainPanel(plotlyOutput("plots", height = "700px"))
  )
)

server <- function(input, output) {

  list_of_plots <- reactive({
    
    purrr::map(input$groups, .f = function(group){

    plot_ly(
      df,
      x = df[[group]],
      y = df$value,
      type = 'violin',
      hoverinfo = 'text',
      showlegend = FALSE,
      box = list(
        visible = TRUE
      ),
      meanline = list(
        visible = TRUE
      ))%>%
      layout(
        autosize = TRUE,
        xaxis = list(automargin = TRUE,
                     tickangle = 80)
      )
  })
})

  output$plots <- renderPlotly(

    plotly::subplot(list_of_plots(), shareX = TRUE, shareY = TRUE)
  )
}


shinyApp(ui, server)

In the app, we have the following behavior, based on the selected groups:

• Group1 + Group2: plot size is adjusted to the longer label in Group2. (the expected behavior)
• Group1 + Group2 + Group3: long label in group 3 gets cut off
• Group1 + Group3: only the labels in Group1 are used to define the plot size.

In my app, I was able to change the long label to a shorter version, but I was wondering if there is any workaround around this problem.

Comienza ejecutando el reprex de R/Shiny proporcionado e inspeccionando plotly::subplot() junto con las configuraciones xaxis automargin y tickangle. Se considera terminado cuando las etiquetas más largas del eje x siguen siendo visibles al seleccionar Group1, Group2 y Group3, incluido el caso Group1 + Group3.
