Component used: Navigation
Version used: 1.0.0-alpha11

I'm seeing some strange behaviour when pressing back button and transistion back to a fragment from a fragment of the same id.
My app uses some generic fragment structures that are driven by args passed in, as such there are places like:

FragmentA -> FragmentB -> FragmentB -> FragmentC

However if the back button is pressed on the second instance of FragmentB, FragmentA is replaced in the navhost while the navgraph correctly displays in the toolbar. Forward navigation from this point however is missing from the navgraph and results in an IllegalStateException with the action 'not found' in the graph, unless the back button is pressed again (pushing the navgraph destination back to FragmentA)

Is this intended behaviour? If so is there a way to declare FragmentB as 'stackable'?

Status is still Assigned, but Compose 1.1.0 was already released. Did the ETA change for this feature?

The Compose Animation APIs Navigation needs (such as AnimatedContent) are still @Experimental in Compose 1.1.0.

seriously no update on what is stable?

AnimatedContent is, as of today, still experimental and still cannot be used in androidx.navigation.

As soon as it is stable, we can kick off this work.
