When using the new "wikitext" language tag on a text that includes a wikilink with a colon, the color is incorrectly applied to the text. The part up until the colon is in blue, while the text after is in green.

Expected: the complete text inside the wikilink is green.

Steps to reproduce:
<syntaxhighlight lang="wikitext">
[[Homicide: Life on the Street]]
</syntaxhighlight>

Result:
