This issue can be noticed in all custom node editor addons (Animation Nodes, Sverchok, etc...)

Steps to reproduce:

• Open a custom node editor (for example, Scripting > Text Editor > Templates > Python > Custom Nodes, then execute the script to register a custom node editor)
• Switch editor type to the custom node editor
• Add a node tree and add a node, try to animate a value or use drivers
• You can see both are not working, where as in Shader Editor or anywhere else they work
