### Godot version

4.0 stable

### System information

Manjaro Linux, kernel 6.1.1-1-MANJARO, AMD Ryzen 5 3600, AMD RX 580

### Issue description

The `wrap_mode` property of the `TextEdit` node doesn't seem to really do anything. Setting it to `LINE_WRAPPING_BOUNDARY` simply means that there won't be an horizontal scrollbar if the text overshoots the boundary, instead of actually forcing the text to the next line so that it stays visible.

### Steps to reproduce

Create a TextEdit node and set its `wrap_mode` property to `LINE_WRAPPING_BOUNDARY`
