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

Nobody has claimed this yet.

**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.

Start by reproducing the three-screen flow described in the issue on Android API 30 with Material Library 1.3.0, using the linked video as a reference. Trace how the Material Container Transform is configured when opening Screen 2 and then Screen 3; done means Screen 2 retains its launch settings and returns with the same transition.
