/**

* This module allows passing require modules instances to
|
||
|
|
* embedded iframes in a page.
|
||
|
|
* For example, if a page has the "plugins" module initialized,
|
||
|
|
* it is important to use exactly the same "plugins" instance
|
||
|
|
* inside iframes as well. Otherwise, plugins cannot save any
|
||
|
|
* state.
