This will naturally resolve itself when we lift the namespace-specific restrictions on editing the Wikitext and can use the editing API instead of going through the back door, as we do now.
This is related to bug 37844 - in that these will both be resolved in the same way.
Assigning this to a release milestone so it's clear when at the latest to expect it to have been fixed; it may have been fixed beforehand.
