After the last update (following versions of the Blue Ocean plugins):

• Blue Ocean - Version 1.27.16
• Blue Ocean Core JS - Version 1.27.16
• Blue Ocean Pipeline Editor - Version 1.27.16

The "Display the login new window" option that was available on a step level in a stage is no longer present.
This option still exists for the whole stage, but it seems to have been removed for the steps.

Is it possible to bring it back, please?

There are a few screenshots in the attachment section.
