Coupling tooltips on hover between subplots using r and plotly

I would like to do a plot like this one: https://www.somesolvedproblems.com/2020/03/how-to-link-plotly-events-between-plots.html

Here is what I have tried:

library(tidyverse)
library(htmlwidgets)
library(ggplot2)
library(plotly)
library(shiny)

x <- seq(0,1, 0.001)
y <- sin(2*pi*x)
z <- cos(2*pi*x)

df <- data.frame(x = x, y = y, z = z)

p <- ggplot(df, aes(x, y)) + geom_line()
q <- ggplot(df, aes(x, z)) + geom_line()


r <- subplot(p
           , q
           , nrows =1
           , titleX = FALSE
           , titleY = FALSE)

r$elementId <- "rt"

s <- r %>%
    onRender("
    function(el) {
    el.on('plotly_hover', function (eventdata){
    console.log(eventdata.xvals);
    Plotly.Fx.hover('rt',
                    [
                        { curveNumber: 0, pointNumber:eventdata.points[0].pointNumber },
                        { curveNumber: 1, pointNumber:eventdata.points[0].pointNumber },
                    ]
    );
    
    }
  ")

with hints from: https://community.plotly.com/t/coupling-hover-events-for-side-by-side-subplots/2049 and https://plotly-r.com/js-event-handlers.html

However, this does not work yet. Primarily, because of my lack of understanding of the javascript issues. Is such bidirectional trigger possible? Can this be done using plotly package and related tools such as htmlwidgets and htmltools package for r? Thanks.

Issue không cung cấp tệp nào trong repository hoặc điểm bắt đầu của test. Trước tiên, hãy tái hiện ví dụ R bằng subplot(), htmlwidgets::onRender() và Plotly.Fx.hover(), sau đó xác định hành vi hover hai chiều được hỗ trợ và một ví dụ hoặc test có thể thực thi làm tiêu chí hoàn thành.
