Fires when the dashboard section registry hydrates, on its first read after `init`. Register sections here rather than on `init`: the registry is read from wp-admin and from REST, and each path loads it at a different moment. A registrant that may run twice guards with `is_registered()`.
Parameters
- $registry
Dashboard_Section_Registry The registry being hydrated.
Changelog
- Introduced in Jetpack 0.9.0
