Agent Server Parameter does not affect Freestyle project's job node selection.

System:

• Jenkins 2.289.2 LTS from docker container
• Several connected windows agent nodes
• Pluging 'Agent Server Parameter'
• Freestyle project project
• Admin login

Steps to reproduce:

1. Open project
2. Click 'Configure' to change project configuration
3. Check 'This project is parameterized'
4. Click 'Add Parameter'
5. Select  'Agent Server Parameter' and set 'name' e.g. 'agent-node'.
6. Save project configuration
7. Click 'Build with Parameters'
8.  For 'Agent Server Parameter' select non-default node name.
9. Press 'Build' button
10. Find started job and open the build page

Expected result: new build agent name should be the same as set in 'Agent Server Parameter'  'name' .

Actual Result: the actual new build agent name is different from selected name...

Meantime, NODE plugin allows to select desired node as expected...
