BUGFIX: Prevent augmenter from applying data of multiple nodes into t…

…he same element

9.0 port of neos/neos-ui#3856

Original Commit MSG:

This fixes a regression introduced in #b56135a01ecf59ae3a4990e3fd54ac766732e0e6 which
removed the script tag, causing the augmenter to add the data of multiple nodes into the same
html element in certain cases instead of adding an outer div.

With this change this behaviour is now more explicit instead of relying on the inner workings
of the augmenter.
