Incorrect link generated sub-namespaces

The [`devtools.panels`](https://developer.chrome.com/docs/extensions/reference/api/devtools/panels) namespace has a method called [`setOpenResourceHandler()`](https://developer.chrome.com/docs/extensions/reference/api/devtools/panels#method-setOpenResourceHandler) that links to [`devtools.inspectedWindow.resource`](https://chrome.devsite.corp.google.com/docs/extensions/reference/api/devtools/inspectedWindow#type-Resource). For some reason it's rendering the last part of the link as `devtools_inpsectedWindow` instead of `devtools.inspectedWindow`.

I suspect this is a problem with links to namespaces that contain namespaces: `devtools`, `enterprise`, `input` and `system` specifically.
