MultiplayerSynchronizer modifies value independently of property setter

Issue description

When synchronizing a property with MultiplayerSynchronizer, the value is modified before the setter is called. Example:

var health : int = 100:
	get:
		return health
	set(value):
		if not $MultiplayerSynchronizer.is_multiplayer_authority():
			prints("set health", health, value)
               health = value

Modifying the value calls the setter, but with the value already being replaced:

set health 100 100
set health 85 85
set health 70 70
set health 40 40

Steps to reproduce

Standard MultiplayerSynchronizer setup with a node that contains a property like above

I'm unable to reproduce, I used the project in #62961 .
Edited the script to add:

@export
var setter_value := 0.0 :
	set(value):
		if not is_multiplayer_authority():
			printt(setter_value, value)
		setter_value = value

Then I started adding process delta to the value server-side.

Which resulted (client side) in:
