[BUG] FMV note not rendered correctly in generated specification.

[mgabka]

Describe the bug
The source text from

acle/main/acle.md

Line 2511 in 996abdb

[^fmv-note-names]: For example the `sve_bf16` feature depends on `sve`

is not rendered correctly in the generated ACLE specification and in the preview.
The preview does not show the 2 lines at all, while the generated release version has just 1 line, https://arm-software.github.io/acle/main/acle.html#function-multi-versioning despite the acle.md having both.

To me looks like it is issue with "fmv-note-names".
