This is related to #39297. In particular, the README in https://pkg.go.dev/mod/github.com/tachyon-protocol/[email protected] doesn't have a space/newline before the fenced code block, causing blackfriday to not detect this as a code block.

Using the same code I posted in the linked issue above with minor tweaks, I managed to confirm that this is indeed the case, and that adding a newline before the fenced code block will allow blackfriday to correctly detect and render the code block. I also tried using goldmark on the readme without adding the space/newline before the code block, and goldmark still correctly identified and rendered the code block.

Closing as a duplicate of #39297.
