ID 405661 - NetworkMaterialCreate: Connecting/disconnecting shading node ports wrongly collapses shading node

Problem summary:

Connecting or disconnecting node ports causes a node to automatically collapse when one of the nodes has the edit flag set and the Parameters tab is open.

Steps to reproduce:

• Load the Lighting layout in Katana
• In the Node Graph tab, create a NetworkMaterialCreate node, and enter it.
• Create two shading nodes, e.g. dlRandomInputColor and dlPrincipled.
• Set the edit flag on one of the shading nodes to show that node's parameters in the Parameters tab.
• Expand some of the pages on the shading node.
• Connect the two shading nodes on one of the ports that has just been expanded to.

Expected behaviour:

• Ports connect.
• Nodes remain expanded.

Actual behaviour:

• Ports connect.
• Node collapses. 

Workaround:

• Close the Parameters tab before making connections between shading node ports.
• Clear the edit flag from the shading nodes before making connections.

Tested versions/platforms:

• 3.2v1 - Affected
