/**
 * Detect an attempt to paste plain text or wikitext, and allow it to be directly pasted without escaping it.
 *
 * This handler is only registered in source mode, as that's the mode where users are interacting
 * with the plain-text equivalent of the content already. Without this handler, a paste with `text/plain`
 * and `text/html` content would take the html content, run it through the normal paste flow, then convert
 * the resultant HTML into wikitext via parsoid. This would have the side-effect of escaping any wikitext
 * content that's in the paste with nowiki, which probably isn't what the paster actually wants.
 *
 * We also catch anything which has `text/x-wiki`, since it has explicitly come from a source-mode part
 * of VE, and contains something that's definitely wikitext.
