Fenced code block breaks rendering on Firefox

[wormsky]

If I include a fenced code block in my markdown file only the first one is rendered, and all the rest of the file is ignored.

Here is an example file and the associated rendering.

Content of the file:

Title

Subtitle

import math

print(math.pi)

Result:

I'm using version 5.3 on Firefox 115.15.0esr

Ooooops I'm sorry I think I already found the issue, I had another markdown extension that appears not to cohabitate well, I disabled it and everything is fine, sorry for the inconvenience.
