Behavior setup is ignored (deactivating mouswheel and allow fullscreen)

I deactivated the mouse wheel support in the behaviour tab of the preset I specified in the OpenLayers WKT widget configuration as the one I want to use for input. But the mousewheel is still working and drives me crazy. I also wanted to have the fullscreen mode but this is ignored as well. Is it generally not possible to change behaviour things on the map which is used by the WKT field?

The preset which is used is the right one I think because all the configuration I did on the "Center & Bounds" tab is working properly. Also if I show the preset on a node the mouswheel is deactivated and the fullscreen icon is available.

Is it a bug? Is it not possible? Or I am missing something?
Thanks and regards.
