No
Changes made to a variable of a Script are not saved when they are made inside the Prefab Mode even with Autosave enabled
How to reproduce:
1. Open "TestFailingUnity2018-3-b4" Project.
2. Select "GameObject" which is a Child Object in Canvas -> GameObject (1)
3. Enter the Prefab Mode for "GameObject"
4. Change the Quantity in the Inspector Window under the "PRL Collection" Script
5. Exit the Prefab Mode - Quantity is not updated
Reproducible with: 2018.3.0b10, 2019.1.0a9
Earlier releases of Unity don't support Nested Prefabs
Expected Result: Values from a Script are saved from the Prefab Mode when Autosave is enabled
Actual Result: Values from a Script are not updated in the Inspector Window and changing quantity further freezes Unity Editor
Note: trying to change values in the Editor again will cause Unity to freeze. GameObject in the Scene has Children created from within both the Prefab Mode and Scene Hierarchy.

Resolution Note:
You need to make sure the PrefabStage's scene is dirtied (so saving will kick in) when modifying the PrefabStage objects without using SerializedProperties. To dirty the PrefabStage's scene try the following:
var prefabStage = PrefabStageUtility.GetPrefabStage(yourGameObject);
if (prefabStage != null)
{
EditorSceneManager.MarkSceneDirty(prefabStage.scene);
}
