Please use cooldown branch here instead of main:

@adaussy The cooldown branch has been rebased over SysON 2025.10.6 (and SW 2025.10.6)

[AxelRICHARD]

I've rebased the PR on top of the latest version of the cooldown branch.

Here some points you need to address:

• add a screenshot of the new popup in the doc and the release note
• the new elements have the same elementId than their origin. elementIds should be different.
• ElementContainmentFeatureProviderDelegate, SysMLContainmentMembershipLabelSwitch, SysONDuplicateDelegate, SysMLContainmentMembershipLabelSwitchTest have been added in syson-application-configuration. are you absolutely sure this is the appropriate place? Why it is not in syson-tree-explorer-view? Is there some cases where those services will be used by something else than the Explorer view?
  Thank you.

Why did you delete this line?

[adaussy]

Sorrry, it should be belong to thid PR. I will remove it and create another PR.
This line makes the IntelJ Checkstyle plugin fail. Since this rule is ignored I simply remove it so I can now use checkstyle inside my IDE.

[AxelRICHARD]

It's strange, you seem the only one to have the problem. Can you double check with another person please?
