No fonts detected for basic plot

[memeplex]

Describe the bug

r$> hist(c(1,2,3,1,2,3))
Warning message:
No fonts detected on your system. Using an empty font. 

My config:

"r.plot.useHttpgd": true

The output:

Expected behavior

Outside vscode-R this works as expected. It seems to be that my font setup is not correctly set for httpgd.

Environment (please complete the following information):

• OS: macOS Sonoma 14.3.1
• VSCode Version: 1.87.2
• R Version: 4.3.3
• vscode-R version: 2.8.2
