Description Amir E. Aharoni 2012-03-12 09:06:07 UTC
In an RTL Wikipedia a heading like "==<span dir="ltr">C++</span>==" shows correctly as a heading in the text flow, but it is shown as "++C" in the table of contents, because the <span> tag is omitted and an RTL direction is assumed.

Not all HTML is omitted - a heading like "==E = mc<sup>2</sup>==" shows correctly both in the heading and in the table of contents.

Confirmed on 1.19wmf1. From the parser:

    $tocline = preg_replace(
        array( '#<(?!/?(sup|sub|i|b)(?: [^>]*)?>).*?'.'>#', '#<(/?(sup|sub|i|b))(?: .*?)?'.'>#' ),
        array( '',                          '<$1>' ),

Those regexen are rather ugly, but let's see if we can't add a very limited allowance for span:

    $tocline = preg_replace(
        array( '#<(?!/?(sup|sub|i|b|span dir="ltr")(?: [^>]*)?>).*?'.'>#', '#<(/?(sup|sub|i|b|span dir="ltr"))(?: .*?)?'.'>#' ),
        array( '',                          '<$1>' ),

But I have to ask - someone went through the effort of not having a ?> in that regex in two different places, and then left a ?> in another place, and I notice that the world hasn't exploded.

This is still an issue. not critical, but annoying.
