Don't show Inspector tabs that don't pertain to a selected object #7959
Description
Is your feature request related to a problem? Please describe.
Many sub-objects of views, when clicked, invoke Inspector tabs (like the Styles tab) that don't pertain to them, such as Time Strip swimlanes and their sub-objects.
Describe the solution you'd like
Selectable objects and sub-objects should have a method to disallow "standard" Inspector tabs that don't pertain to them.
This feature is required for #7936
