That shows that this comment is added in multiple places, but (you cannot see this in this dump) all exts except the <syntaxhighlight> one don't have the outer <p> wrapper in the output ... so, this patch only ensures that the p-wrapper stripping continues to work. 

If we want to actually strip out that trailing comment in all cases, we'll probably need more careful work, since in the general case, we don't know if that trailing comment is actually added by the extension or by the parsing code in core, and we don't want to hardcode for specific comment values either.

The comment itself should be harmless since it is rendering-transparent and pretty much all passes ignore them. There may be the occasional extra newline in output. But, we can separately investigate if there is a way to have the parse call to core not add this comment by passing in an appropriate flag / option.
