Creating GameObject in FixedUpdate doesn't exit the FixedUpdate Interpolation context

[PolSpock]

Describe the bug

According to this discord discussion with conna,

Currently creating a GameObject in an OnFixedUpdate() will not leave the fixed update interpolation context, creating some confusing behavior between the OnUpdate and OnFixedUpdate behavior

Let's take a look at the reproduction steps

To Reproduce

1. Download https://github.com/PolSpock/sbox-updatefixedupdate/tree/main/code
2. Look at NetworkTest.cs, it's the player component.
   By pressing attack1, 2 identicals gameobject will be spawned :

• One from OnUpdate context
• One from OnFixedUpdate context

Money.cs is just a simple GameObject with a MoneyChild child GameObject who rotating on himself & has Transform.LocalRotation = Rotation.FromPitch( 90f ); on OnAwake

3. Starts a game, look at the log : the transform are different between the 2 gameobjectfs cause the OnFixedUpdate aren't leaving his interpolation context even if the GameObject is in his OnAwake context

This is confusing.

Expected behavior

As conna says :

it makes sense we shouldn't be interpolating values set in OnAwake etc just because we're in a fixed update context, when you are setting transform in OnAwake you'd expect it set immediately regardless

Also, note this issue only happens if i'm spawning the Money.cs component that will spawn his ChildMoney.cs in his OnAwake func.

If I'm spawning directly ChildMoney.cs the issue does not seem to occur

weird

Can you try to reproduce this when the next Steam build finishes @PolSpock ?
