Don’t open the AI Assistant tab by default because it was opened in a recently closed step inspector view

[christad92]

The current behavior of the inspector is that we store the active tabs of a recently closed inspector so that the next time the user opens the inspector, the tabs should remain active. For the input panel, we want the input tab to be active by default at all times when the inspector is opened.

Users should only open the AI Assistant tab when they need to.
