When I put syntax errors into a Lilypond window in VE, I get a <span> with the Score-compilererr error message and a <pre> with the Lilypond compiler output in English. The <pre> doesn't have lang="en" dir="ltr", so in the Hebrew Wikipedia I see it in the wrong direction. The <span> with the localized error must remain as it is, but if the text in the <pre> is always in English, the HTML element must have lang="en" dir="ltr".
