[TYPO3] imageorient default for Text w/image

[Pascal]

Hi,

I am trying to set the default for the image orientation in the Text w/image.
In my Page TSconfig:
   TCAdefaults.tt_content {
       imageorient = 26
   }

This does the trick for a single image (not Text w/image).
Is this a bug or should I use a different TCAdeafult?

Thanks in advance,
Pascal
