Description

The html comment at the begin of a page, leaves a newline and this newline can produce a paragraf.

The wikitext:

<newline>
<newline>
text

produce a paragraf at the top of page and is parsed the same way than

<newline>
<newline>
text

But it better to parse it like

<newline>
text

and produce no paragraf.

Thanks.

Looks like expected behavior to me.
I see your point, but there's probably some case where that newline shouldn't be stripped.

I have found in Preprocessor_DOM.php:

TODO: This could theoretically be done if $wsStart == 0, i.e. for comments at the overall start. That's not how Sanitizer::removeHTMLcomments() did it, but it's a possible beneficial b/c break.

looks related: bug 4161
