### Godot version

4.2 dev4

### System information

Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1060 (NVIDIA; 30.0.15.1403) - Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz (8 Threads)

### Issue description

When you write a text in LineEdit (e.g. in the inspector) and the text is long enough to be scrolled, and then you delete all text with Ctrl + A -> Backspace, writing again will not show the first character.

### Steps to reproduce

- add some node with a single-line text property
- edit the property, write something that doesn't fit the LineEdit width
- Ctrl + A -> Backspace
- write something again
