Thanks for the detailed setting. I could also reproduce the behavior.
As the "Open Message" button action shows a message in a pop-up window, the target tag might be ignored.
How about using "External Link" button action?
The action can open an external link from a button in a different tab without a specific configuration.
If you would like to open a new tab from a message in the pop-up window, please open a support case.
Thanks.

Thanks for your answer.

 

I will open a support case for this. The button action "External Link" is not where I am looking for
