[skwasm] Failed cherry pick for `Fix platform view placement`

[Rexios80]

Cherry-pick issue: https://github.com/flutter/flutter/issues/154345

This cherry pick does not seem to have applied properly. Either that or it depends on other changes from master that also need cherry picked. I confirmed multiple times that this issue is still present in Flutter stable 3.24.3 but not master.

Steps to reproduce:

1. Be in the camera plugin example: https://github.com/flutter/packages/tree/main/packages/camera/camera/example
2. Be on Flutter version 3.24.3
3. Run flutter run -d chrome --wasm
4. Observe the bad platform view placement
5. Be on Flutter master
6. Run flutter run -d chrome --wasm
7. Observe the correct platform view placement
