Worked: Never, the issue is present in 4.1.1 and 4.2.1

Short description of error
The 'Menu Switch' node allows for picking an enum value via a 'Menu' socket.
A default value can be chosen for a 'Menu' socket.
This default option isn't always respected, and there are at least two issues with it:

Using the 'Reset to Default Value' operator doesn't respect the default value. It instead seems to always default to the first value that was created for the enum (index 0).
Rearranging the enum 'Menu Items', or removing a 'Menu Item' doesn't seem to update the indices.

Exact steps for others to reproduce the error
Setup:

Make a new geometry nodes modifier.
Make a menu switch node
Hook up a Menu socket from the Group Input node.
Hook up some values into the menu switch (See the attached .blend file for this basic setup).

Hover over the Menu option in the modifier and hit backspace to use the 'Reset to Default Value' operator.
This works because the menu options were added in order and haven't been rearranged.

Issue #1:
Change the default value of the menu socket.
Try using the 'Reset to Default Value' operator.
It doesn't reset to the default value, instead it resets to the option at index 0.

Issue #2:
Remove the first menu option from Menu Switch node.
Try using the 'Reset to Default Value' operator.
It doesn't reset to the default value, instead it makes the option blank, presumably because it's trying to use the option at index 0 but it has been removed, and the indices haven't been updated.

Rearranging the menu items also doesn't seem to update the indices.

Note: The default value IS respected when assigning the geometry nodes to an object for the first time. Just not when using the Reset to Default Value operator.
