Custom font for source code in flexdashboard

[kbzsl]

The bslib type definition apparently doesn’t have any effect on the source code section in the flexdashboard. But except the source code section, this definition is working fine.

output: 
  flexdashboard::flex_dashboard:
    orientation: rows
    source_code: embed
    theme:
      version: 4
      base_font: "Cambria"
      code_font: "Consolas"

Can you suggest a solution to alter the font for the source code section? Thank you.

I was using for tests a slightly modified example: ggplotly geoms.

The only real change I made was the YAML header:

---
title: "ggplotly geoms using custom fonts"
author: "(adapted from Carson Sievert)"
output: 
  flexdashboard::flex_dashboard:
    orientation: rows
    # social: menu
    source_code: embed
    theme:
      version: 4
      base_font: "Cambria"
      code_font: "Cambria"
---

It is working on a windows machine as the Cambria (serif) font is included by default.

Note: a short code snippet was commented out starting with stuff <- ggplot_build(p) , but the next ggplotly(p) was kept.

On the other hand, after the bslib definitions are added to the YAML header, I am receiving a mysterious warning message, but the output was always created.
