[MaterialContainerTransform] Element transition not being retained when opening a nested screen

Description:
Once we open "SCREEN A" from "HOME SCREEN" with Material Container Transform it works fine and does the return transformation too. But if we open another activity "SCREEN B" from "SCREEN A" then "SCREEN A" loses its transformation settings.

Expected behavior:
"SCREEN A" material container should retain how it was launched and return back in the same transition.

Android API version: 30

Material Library version: 1.3.0

Device: Pixel 2XL

Screenshot/Video:
Screen 1: List of arts
Screen 2: Art details
Screen 3: Artist details

We open "SCREEN 2" by clicking on art on "SCREEN 1", it follows enter and exit material transformation. But when we open "SCREEN 3" from "SCREEN 2" then "SCREEN 2" loses its material transform property.

Inizia riproducendo il flusso a tre schermate descritto nell’issue su Android API 30 con Material Library 1.3.0, usando come riferimento il video collegato. Traccia come viene configurato Material Container Transform quando si apre Screen 2 e poi Screen 3; il lavoro è completato quando Screen 2 mantiene le impostazioni di avvio e torna con la stessa transizione.
