Add RTL rendering support to Markdown (#24816)
Support RTL content in Markdown:
Example document:
https://try.gitea.io/silverwind/symlink-test/src/branch/master/bidi-text.md
Same on GitHub:
https://github.com/silverwind/symlink-test/blob/master/bidi-text.md
`dir=auto` enables a browser heuristic that sets the text direction
automatically. It is the only way to get automatic text direction.
