Extra <p> tags appear in results snippet

[gamov]

Extracted from a search index created by rdoc (4.1.1)

["assert_equal",
   ...
   "<p>Tests if <code>expected</code> is equal to <code>actual</code>.\n<p>An optional failure message may be provided as the final argument. …\n",
null,0]

Those extra p tags appear in the search results (they wouldn't in the past). I tried to look into rdoc why but that gem is quite intricate. The source lines that appear for snippet are treated as RDoc::Markup::Paragraph, I think that's why rdoc add those p tag.
I don't have enough knowledge to fix the source of the problem, but I have a workaround:
In searchdoc.js, change this line (in renderItem):

if (result.snippet) html += '<p class="snippet">' + escapeHTML(result.snippet) + '</p>';

to

if (result.snippet) html += '<p class="snippet">' + result.snippet.split('\n')[0].replace('<p>','') + '</p>';

I actually prefer this since the original line escapes the html making presentation tags apparent in the result...

PS: Why aren't those p tags closed by rdoc?
PS2: http://api.rubyonrails.org is also currently showing the bug
