rustdoc hangs indefinitely on /// <b

[sjackman]

I tried this code foo.rs and ran rustdoc foo.rs:

/// <b
pub fn foo() {}

I expected to see this happen: rustdoc foo.rs to complete.

Instead, this happened: rustdoc foo.rs hung indefinitely.

Closing as a duplicate of #70871. I believe it is waiting for an upstream release of pulldown-cmark.
