No fonts detected for basic plot

[memeplex]

Describe the bug

May be related to #138 but since that one seems to be focused in Linux and remote usage of VSCode I'm not sure.

As I commented in #138 (comment), when using vscode-R with httpgd, basic plots fail to find fonts:

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

And the result doesn't look good:

If I run this in a detached terminal I get no such error and:

Also reported to REditorSupport/vscode-R#1505 because I can't tell whether this is an httpgd issue or just because of its specific setup inside vscode-R.

Environment

• OS: macOS Sonoma 14.3.1
• R version: 4.3.3
• httpgd version: 2.0.1
