How to casing for page headers on GitHub wikis be controlled

githubwiki

Is there a way to escape the apparent forced sentence casing for the title on a GitHub wiki page?

The wiki seems to be based on Gollum, and it seems to force sentence casing for titles. Attempts to change the title to something other than sentence casing, like proper casing for initialisms, (example, attempted change from "Api" to "API") have no effect. Editing the body of the page works fine, though.
