[BUG] ScreenGameplay Background layer or BGA commands not playing before beat 0.

[EngineMachiner]

This issue has been around for a long time.

Describe the problem

When the first BGA is loaded before the beat 0, sometimes:
1.) The commands won't play. ("Init", "On")
2.) The commands get delayed (maybe waiting on the stack and then passing it with a tween) after they pass the beat 0.
3.) The commands are played in the wrong order or some of them are just skipped.

I also noticed that sprite animation is off too.

Describe what should happen

The first BGA should play it's commands normally.

Additional Info
I found out that commands play fine after beat 0, if you change the metrics on the theme or fallback for [Background], with the metric RandomBGStartBeat >= 0
I am not sure but I wonder if there's something wrong with negative beats when a BGA loads.
