[TYPO3-RTE] missing js in 4.0

[Steffen Kamper]

Hi,

i have written an extension using rtehtmlarea in a frontend plugin.
There was no problem in 3.8.1.

Now after update to 4.0 final, i hav a big problem:

The JS in the document's head-section is missing, the other informations are 
written like css and js in/after the form.
I looked at the source but i didn't mentured a difference.

If anyone has an Idea pls help me, thx.
Steffen
