Short description of error
When I set the default value for any input in a custom node group, I would expect to be able to easily reset that input to its default value by clicking "Reset to Default Value," but it always just resets to "0.000," "false," etc. (depending on input type), as though I hadn't set a default.

Exact steps for others to reproduce the error

• Create a custom node group with one or more inputs
• Set a default value for an input (other than 0)
• Exit the node group
• Right-click the value and select "Reset to Default Value"
• Value will reset to "0.000"
