ID 407248 - Dragging nodes on to Group bubbles allows insertion into connections

Problem summary

Dragging a node over a connection between two nodes in a Group bubble will highlight the connection yellow indicating that the node can be inserted into the connection and be placed into the Group bubble. Placing the node will insert it into the connection, but not place the node into the Group bubble. This causes the connection to leave the Group bubble to the node and then re-enter the Group bubble.

Customer reported version
Katana 3.1v5

Customer reported platform
Unknown.

Steps to reproduce
1) Create 2 Material nodes in the Node Graph.

2) Connect the first Material node to the second.

3) Select both Material nodes and group them with the 'G' shortcut key.

4) Expand the Group bubble by clicking the plus icon on the Group node.

5) Create a new Material node and drag it over the connection in the Group bubble.

Expected behaviour
There will be no indication that the node can be inserted into the Group bubble or the node gets place into the Group bubble and connects between the existing nodes.

Actual behaviour
Placing the node will insert it into the connection, but not place the node into the Group bubble. This causes the connection to leave the Group bubble to the node and then re-enter the Group bubble.

​​Workaround
Use 'Shift + MMB' and drag the node into the Group bubble first, then drag the node onto the connection.
Alternatively, you can Cut the node using 'Ctrl + X' and hover the mouse over the Group bubble and Paste using 'Ctrl + V', then drag the node onto the connection.
