Given the following HTML:

<a rel="mw:WikiLink" href="./]] foo [[bar">Manual</a>

<a href="./]] foo [[bar">Manual</a>

I get [1]:

[[./]] foo [[bar|Manual]]

[./%5D%5D%20foo%20%5B%5Bbar Manual]

The one for external is acceptable (garbage in, garbage out), as it doesn't cause arbitrary wikitext to be passed through.

However the one for mw:WikiLink seems a bug to me. Although it is impossible to link to an invalid link in wikitext (not even with [[<nowiki>invalid </nowiki>]]), that is better than passing through arbitrary wikitext.

That way it at least roundtrips and doesn't mess up the document.

<a rel="mw:WikiLink" href="./]] foo [[bar">Manual</a>

Should serialize to something like:

[[<nowiki>]] foo [[bar</nowiki>|Manual]]

Which parses to:

<a rel="mw:WikiLink" href="./%5D%5D_foo_%5B%5Bbar" data-parsoid="{&quot;stx&quot;:&quot;piped&quot;,&quot;a&quot;:{&quot;href&quot;:&quot;./%5D%5D_foo_%5B%5Bbar&quot;},&quot;sa&quot;:{&quot;href&quot;:&quot;<nowiki>]] foo [[bar</nowiki>&quot;},&quot;dsr&quot;:[1,41,32,2]}">Manual</a>
