[Seaside] How to open a new window/tab with a new root component within the same session?

[Esteban Maringolo]

What would be the proper way to open a new browser window/tab with a
selected component as root component but using the same session?

E.g. I have a main app component and want to open "viewers" (a new
component on a particular model) as root component on the new tab. I
expect the user to interact with this new component, and then likely
to close the tab, the component tree in the main tab should remain
unchanged.

I could see WAInitialRenderLoopContinuation seems to have what I need,
but the whole WARenderLoopContinuation hierarchy is something that I
could never understand and never could find documentation about it
either (e.g. WAPluggableActionContinuation doesn't have any references
in my image).

I'll appreciate any pointer here.
