Setting operator instance name within sub-operator renames parent too

[grant-h]

Describe the bug
Renaming operator instance such as Value within a custom sub-operator type will rename parent when double click was used to descend into sub-operator

Please complete the following information):

• OS: Ubuntu 22.04 (Bottle wine environment)
• Version: v4.0.6.3
• Graphics card and resolution: GTX 1050 Ti

To Reproduce
Steps to reproduce the behavior:

1. Create Value operator
2. Select operator and right click -> combine into new type with name "TestBug"
3. Double click "TestBug" operator to descend
4. Click on Value operator and assign an instance name of "Abc"
5. Ascend out of operator (double click on canvas)
6. Notice that "TestBug" now has name "Abc"

Expected behavior
Only instance assigned name should take it, not parent.
