Tilt: Cannot start game (regression)

[n0samu]

Describe the bug

Since Ruffle nightly 2024-01-07, Tilt's main menu shows up mostly blank, making the game unplayable. This is a regression seemingly caused by #14627.

The error is:

ERROR ruffle_core::timer: Unhandled AVM2 error in timer callback: TypeError: Error #1009: Cannot access a property or method of a null object reference. (accessing field: id)

Expected behavior

The game should work as it did in previous Ruffle builds.

Additional information

The game actually regressed once before in nightly 2023-08-15 due to #12540. The error then was:

ERROR ruffle_core::timer: Unhandled AVM2 error in timer callback: Error: DAE#parseScene: can't find a <instance_visual_scene> element!
        at org.papervision3d.objects.parsers::DAE/parseScene()
        at org.papervision3d.objects.parsers::DAE/parseAfterMaterials()
        at org.papervision3d.objects.parsers::DAE/parse()
        at org.papervision3d.objects.parsers::DAE/load()
        at com.devm.puzzle.level::Level3D/init()
        at com.devm.puzzle::Game/init()
        at com.devm.puzzle::Main/initGame()

But that regression was fixed by #13966, so the game worked fine again until #14627 was merged.

See #10183 for previous issues with this game.
