Write Image as PDF with Box saying "Loading [MathJax]/extensions/MathMenu.js"

Hello,

library(plotly)

n <- 1e3
x <- rnorm(n)
y <- 2*x + rnorm(n, sd = 5)

fig <- plot_ly(x = x, y = y, alpha  = 0.01,type = "scatter")

save_image(fig,"test.pdf")
browseURL("test.pdf")

When I run the above code, I get the box saying Loading [MathJax]/extensions/MathMenu.js，I see the Solution in plotly.py issues 3469:

import plotly.io as pio   
pio.kaleido.scope.mathjax = None

How should I solve it in R？

Bắt đầu bằng cách tái hiện ví dụ save_image(fig, "test.pdf") với plotly 4.10.0 trên thiết lập Ubuntu được báo cáo, sau đó so sánh đường dẫn xuất R với issue 3469 của plotly.py. Kiểm tra cách webshot2 và chromote xử lý trang tải MathJax. Được xem là hoàn tất khi việc xuất PDF hoàn thành mà không có hộp tải và hành vi này được bao phủ bởi một kiểm tra hồi quy phù hợp.
