How to Delete a Node with Custom Type

[Study-boy-dot]

Description:
I am trying to delete a node with a custom type using the asyncua framework. I have reviewed the client-deleting.py example provided in the repository and attempted to implement node deletion in my application. However, I am encountering an issue: after calling delete_nodes, I am still able to access and read the node's attributes like BrowseName.
Code Example:

# Attempt to delete a batch of nodes
await self.client.delete_nodes(self.obj_list)

# Attempt to delete a single node
node = self.client.get_node(self.obj_nodeid)
results = await self.client.delete_nodes([node])  # Delete one node

# Verify if the node still exists
node_after = self.client.get_node(self.obj_nodeid)
try:
    browse_name = await node_after.read_browse_name()
except Exception:
    logger.info("Delete Successfully")

Observed Behavior:
Even after calling delete_nodes, the node remains accessible. I am still able to retrieve the BrowseName using read_browse_name() without any exceptions.

Expected Behavior:
After calling delete_nodes, the node should no longer exist, and attempting to access it should raise an exception.

Additional Context:
The node being deleted has a custom type derived from BaseObjectType.
asyncua version: 1.1.5
python version: 3.8.17
I have stored the nodes in a list and attempted both batch deletion and single-node deletion.
Is there something I am missing in the deletion process? Any guidance or example code would be greatly appreciated.
