Issue description

I am expecting a scaled container to be correctly centered relative to its scaled size using center for anchor preset and alignment but it seems to retain the center coords for the original size

Steps to reproduce

Tested with box containers:

1. Set up control for full screen size
2. Add box container
3. Increase scale on box container
4. Center box container alignment and anchor preset

Expected:
Center is relevant to scaled container

Actual:
Center is relevant to original container size

Expected result would be similar to manually increasing container size and centering as below:

Actual result is offset:

This also affects other canvas items - tested with scaled panel, label, control in place of container

	case PRESET_CENTER:
	case PRESET_VCENTER_WIDE:
	data.offset[0] = x * (0.5 - data.anchor[0]) - new_size.x / 2 + parent_rect.position.x;

new_size is in the local coordinate system of the Control node.
parent_rect.position is in the coordinate system of the parent Control node.
Mixing different coordinate systems is never a good idea.

@Sauermann @AThousandShips I think this is a duplicate of

#19068

Also I see a similar looking issue opened 14d ago

#85668

I guess mine and the more recent ticket can be closed

Thanks for the report! Consolidating in #19068.
