Consider the following wikitext: [[fr:eau]] [[es: eau]] [[ ru:eau]] [[ da: eau]] [[ DE : eau ]] The PHP parser interprets all five of these as interlanguage links, and puts them in the sidebar. Parsoid correctly interprets the first two as language links, but treats the last three as if they had a leading colon.
