Footnote References Not Properly Scoped to Individual Comments

[LangLangBart]

description

When using footnotes in bug reports, they are not scoped to the comment. The
^1 marker always links to the first occurrence of ^1 in the issue.

to reproduce:

1. Open a bug report with some footnotes

foo[^1][^2]

[^1]: bar
[^2]: baz

2. Create a comment on this bug report with a footnote

qux[^1]

[^1]: thud

3. Compare the link on the first footnote in the issue description with the link
   from the footnote from the comment. They are the same.

expected:

Footnotes should have some context/scope like GitHub does it

• GitHub's format: #user-content-fn-1-39ad31d95bf1bd16a061fdbe4a
• Gitea's current format: #fn:user-content-1

additional notes

Additionally, GitHub's styling is superior. In Gitea, footnotes appear small
and cramped when multiple footnotes reference the same word. The actual listing
of footnotes doesn't feel visually distinct enough compared to what users could
accomplish with typical markdown numbered lists and a --- separator.
A smaller font size and a slight grey tone would help.
