When weight of animator layer is set to 0, layer weight is not synchronized in NetworkAnimator

[chromee]

Description

It appears that NetworkAnimator is updating the layer weights at the same time as the AnimationState is updated. However, if the layer weight is set to 0, it seems to stop updating that entire layer. Therefore, if we set the layer weights to 0, NetworkAnimator will not be able to synchronize the layer weights. perhaps the State will also be out of sync ?

Reproduce Steps

1. Create an AnimatorController with two layers
2. Set the NetworkAnimator to its AnimatorController
3. Play and set the layer weight to 0 in the Animator window (do not use the slider, enter 0 directly).

Actual Outcome

Layer weights are not synchronized

Expected Outcome

Layer weights are synchronized

Thank you for your submission of this issue! The video was very helpful. 🥇
NetworkAnimator was not applying the changes to its internal weight table which would prevent the layer weight values from getting set back to the original weight value (for the layer in question). If it was any other value other than the original value, then it would get applied.
A PR with the fix is posted and will be in the update that proceeds the coming v1.6.0 update. 👍
