### System information

Windows 10

### Issue description

Anchors presets are ignored, sometimes they work if you manually modify the size of the node using the handles.

### Steps to reproduce

Simple test, open new scene, base node is Control, try to set the full rect preset, nothing happens. then just try out different stuff with different nodes and hierarchies, it barely works.

### Minimal reproduction project

	hint_filler_right->hide();
