[Neos] Content element controls disappearing

[Lorenz Ulrich]

Hi everyone

I've been working with custom content elements (Youtube, Soundcloud) and 
a gallery plugin from Lelesys now and I've encountered several times 
that the node controls just disappeared after inserting such an element. 
Therefore I cannot delete the node or add new nodes.

Did you also encounter such a behaviour? Do you know a solution?

Best regards,

Lorenz
