### Godot version

4.0.2.stable, 4.0.3.stable

### System information

Win10, i7-10870H, Intel UHD Graphics / GeForce RTX 3060 Laptop(31.0.15.3203)

### Issue description

In Compatibility mode Control nodes (tested Label, Button, LineEdit, RichTextLabel, probably others) with imported Font with LCD subpixel antialiasing enabled messes up non-standard font-color if there is Control with default font (or non LCD subpixel antialiased) present. It also somehow depends on node hierarchy and which nodes are currently visible.

### Steps to reproduce

1. import any font and enable LCD subpixel antialiasing for it;
2. Create at least 1 control with text with this font and at least 1 for default or non-LCDspa so that LCDspa font precedes non-LCDspa one in hierarchy;
3. Change default color for LCDspa font;
4. Move around so that you see only LCDspa node or both and observe unintended color change;
5. (optional) other LCDspa node positioned after non-LCDspa in hierarchy prevents color change when visible.
