plot in External browser trigger error of “useMethod”

[liuhuoz]

Describe the bug
When open an external browser (in case, Google Chrome), and draw a ggplot2 plot, the plot would not draw or in a wired way that elements are disrupted. Further, the terminal show message like:

Error in UseMethod("depth") :
  no applicable method for 'depth' applied to an object of class "NULL"
Error in grid.Call.graphics(C_upviewport, as.integer(n)) : 
  cannot pop the top-level viewport ('grid' and 'graphics' output mixed?)

However, after closing the browser, everything come back to normal.

Besides, directly using Radian without vscode and httpgd::hgd() function to open an external browser would not response such error.

To Reproduce
here is my test code

data <- data.frame(
  x=rnorm(10), 
  y=rnorm(10)
)
data
p <- 
data %>% 
  ggplot(aes(x=x,y=y))+
  geom_point(size=10)
p

Steps to reproduce the behavior:

1. draw a plot in vscode windows
2. Click on 'Open in External Browser'
3. draw another plot
4. See error

I have the same problem. Seems to have started since httpgd was "revived" and the plotting split out into unigd.

I have the same problem. Seems to have started since httpgd was "revived" and the plotting split out into unigd.

Recently I draw the chord picture with the package "circlize" which is not a ggplot-based drawing system. When plotting in both vscode and bowser, it doesnt trigger any problem. However, when I draw other pic with ggplot2 in the same drawing dev, the error happened.
It seems like a quite complex problem, and may relate to many packages, vscode-R and vscode itself.
