Maniac: loaded save files with a String Picture on layer 8 or 9 will be displayed on the save loading screen

[Mimigris]

Player platform: Windows 11, latest continuous build of the Player.

Describe the issue in detail and how to reproduce it: In a game where Maniac patch is enabled, display a string picture on the layer 8 or 9, and create a save. If you try to load the save file using the load menu (title screen or command), upon selection of the save file, the string picture will be able to be seen during the transition while it should not.

You can test it in this test project: display a string picture, save, then load the save file to see it in action. Save File Layering.zip

This problem doesn't seem to happen with regular pictures.
