Problem

Footnote lines, when written on adjacent lines, squish into a single footnote:

//! [^1]: Footnote A.
//! [^2]: Footnote B.
//! [^3]: Footnote C.

Steps

1. Copy-paste the following snippet at the top of a new module:

   //! Reference to footnotes A[^1], B[^2] and C[^3].
   //!
   //! [^1]: Footnote A.
   //! [^2]: Footnote B.
   //! [^3]: Footnote C.

2. Run cargo doc.

3. Observe that the footnotes have been incorrectly rendered as a single footnote.

Possible Solution(s)

No response

Notes

One workaround is to separate the footnotes with empty lines:

//! [^1]: Footnote A.
//! 
//! [^2]: Footnote B.
//! 
//! [^3]: Footnote C.

It's not pretty, though.
