wrong permalink to html heading in markdown file

[milahu]

Description

in a markdown file, put the html heading

<h1>Heading without ID</h1>

then gitea blob API will generate the wrong permalink # for that heading.
github blob API would generate the permalink #heading-without-id

if the html heading has an id
gitea blob API renders the correct permalink #heading-with-id

<h1 id="heading-with-id">Heading with ID</h1>
