Description

While playing with RESTBase I noticed an odd block of HTML at the end of the enwiki's Main_Page:

Something similar is in parsoid's HTML:

It's mostly meta tags but the <pre> tag is unexpected.

The HTML is coming from wikitext templates and magic words at the end of enwiki's Main_Page:

<!--        INTERWIKI STRAPLINE        -->
<noinclude>{{Main Page interwikis}}{{noexternallanglinks}}{{#if:{{Wikipedia:Main_Page/Tomorrow}}||}}</noinclude>__NOTOC____NOEDITSECTION__

Normal parsing and action=render do not generate any HTML for this wikitext.

Gabriel asked me to file this bug, commenting

that might be incomplete CSS or JS
the RL URL referenced by Parsoid for CSS isn't exhaustive
although, it's odd that there's a pre in there

If you expand {{Main Page interwikis}}, you end up with wikitext that looks like this example,

<noinclude>[[simple:]] [[ar:]]</noinclude>__NOTOC__

The space in between the interwikis puts us in the pre-start state (the other noinclude and the simple interwiki are SOL-transparent).

@Arlolra, the point is that this differs from the PHP parser output. We already have code in Parsoid that suppresses pre if a line only contains category links and spaces; we'll probably want to extend this behavior to page properties like __NOTOC__.
