[TYPO3-core] RFC: #9596: htmlArea RTE does not work in IRRE subelements

[Stanislas Rolland]

Reminder #1

> This is SVN patch request.

> Type:
> Bugfix
> 
> Problem:
> When using htmlArea RTE in IRRE subelements, RTE just shows that it is 
> loading (forever). So it is not possible to use RTE in IRRE subelements.
> 
> Related issues:
> 1. RTE stylesheets will not be loaded if the first RTE instance is 
> created as a result of an IRRE ajax call;
> 2. in the same case as 1, js scripts may sometimes be loaded and 
> executed in the wrong order;
> 3. when multiple children are created, RTE may never load in the first 
> instance;
> 4. when multiple children are created, a SYSTEM ERROR alert may be 
> triggered on save.
> 
> Solution:
> Avoid re-initialization on Ajax call.
> Ensure synchronous execution of scripts.
> Load stylesheets when the first instance of the RTE is loaded through 
> Ajax request.
> Remove any reliance on RTEcounter as RTE instance identifier.
