copy&pasting into gridelelements is not working anymore
Copy&pasting content into gridelement elements is not possible anymore -
neither via left-click-context-menu (the "paste into"-option is missing),
nor via the Paste-Button besides the (+content)-button.
The content is pasted on top of the normal column,
it seems that the gridelements-specific values colPos and tx_gridelements_container values are not set correctly anymore.
