process_markdown_to_html causes tokio-runtime-worker to panic

[khanhtimn]

Describe the bug
I am using femark to render html in my leptos blog. femark::process_markdown_to_html causes tokio-runtime-worker to panic IF there are code block(s) in the input. I'm sorry if it's inappropriate to open an issue here but I have been looking at your leptos blog for reference and this issue seems specific enough, sorry for any inconvenience.

Leptos Dependencies

leptos = { version = "0.7.0-rc1", features = ["nightly"] }
leptos_meta = { version = "0.7.0-rc1" }
leptos_router = { version = "0.7.0-rc1" }
leptos_axum = { version = "0.7.0-rc1" }
axum = { version = "0.7", features = ["macros"] }
femark = "0.1.6"
sqlx = { version = "0.8", features = [
    "runtime-tokio-rustls",
    "macros",
    "postgres",
    "chrono",
] }

Expected behavior
Code block should render without panicking the server.

Additional context
Any other inputs are processed correctly and return the correct html.
I'm not really sure if this has to do with leptos's server function or my implementation with sqlx though.
