Markdown supports syntax highlighting hints on code blocks. But when I use a dark theme, PyLova seems to be rendering all code blocks that have syntax highlighting with a light background and light text. This often leads to most of the code in the block being entirely illegible because it is nearly the same color as the background. It seems that the text is being rendered in dark mode as it should, but for whatever reason, the background of the code block is using the light mode background.

Random example, here are some lines taken from https://codeberg.org/quokkau/PyLova/src/branch/main/app/instance/routes.py to use as glorified lorem ipsum to help illustrate the issue:

from collections import namedtuple  

from flask import request, url_for, g, abort, flash, redirect, make_response  
from flask_babel import _  
from flask_login import current_user  
from sqlalchemy import or_, desc, text  

from collections import namedtuple  

from flask import request, url_for, g, abort, flash, redirect, make_response  
from flask_babel import _  
from flask_login import current_user  
from sqlalchemy import or_, desc, text  

This is what those two code blocks look like with dark mode enabled:

The first code block looks fine, just there is no syntax highlighting (which is not a problem at all, as that is indeed what the Markdown is). But the second code block looks illegible because I had specified that the code block is Python, which makes the code block use syntax highlighting and for whatever reason use dark mode text colors with a light mode background.

As a refresher, a code block is added in Markdown using three backticks before and after the code block:

```  
code  
goes  
here  
```  

And to use syntax highlighting, you add a language hint after the first three backticks:

```py  
python  
goes  
here  
```  
```c  
c  
goes  
here  
```  
```rust  
rust  
goes  
here  
```  

I think this is an issue that is specific to PyLova because if I check a post that has code block with syntax highlighting on here and on a PieFed instance, it looks fine on PieFed and only looks wrong here. Example:

• PieFed: https://piefed.ca/c/360cameras@piefed.social/p/905011/a-simple-script-for-viewing-panorama-images
• PyLova: https://quokk.au/c/360cameras@piefed.social/p/1143387/a-simple-script-for-viewing-panorama-images

If it helps you chase down the offending commit or anything, I think I had initially noticed this start happening suddenly a couple months or so ago.

If you think it would be worthwhile/helpful, I can make a Codeberg issue about this.
