Arguments under Node Properties tab disappear when adding job

Current Situation:

• The use case for node arguments includes using the same job a number of times in a given workflow with different parameter sets.
• When we add arguments under Node Properties Tab it disappears after adding a new job while keeping the previous job selected.

Steps to reproduce:

• Create a new workflow W and add a job: job1 to it.
• Add arguments to Node Properties .
• Now while keeping the job1 selected add a new job: job2. to the W.
• Now if you Observe then you find out that job1 has lost its Node properties.

Desired Behaviour:

• When we add arguments under Node Properties Tab it should not disappears after adding a new job while keeping the previous job selected.
