### Godot version

v4.1.beta.custom_build [afe65de11]

### System information

Debian Linux 12 Xfce

### Issue description

For an exported `PackedVector2Array` I am unable to select a different entry field with a mouse-click after an edit.

I have verified, that reverting #76711 fixes this issue.

### Steps to reproduce

1. Load and run MRP
2. select the main node in scene tree
3. Expand the `mypacked` variable in the inspector
4. click lmb on "Add Element"
5. click lmb in the x-entry-field
6. enter number "1"
7. click lmb in the y-entry-field

After 7 I would expect that the y-entry-field is selected, but no entry field is selected.
