text cursor is invisible when renaming nodes on BSPWM

### Tested versions

reproducible in 4.2.1.stable.mono and 4.1 iirc

### System information

Godot v4.2.1.stable.mono - Arch Linux #1 SMP PREEMPT_DYNAMIC Fri, 23 Feb 2024 16:31:48 +0000 - X11 - Vulkan (Mobile) - dedicated NVIDIA GeForce RTX 3060 Ti (nvidia; 550.54.14) - AMD Ryzen 5 7600X 6-Core Processor (12 Threads)

### Issue description

the I-shaped cursor that appears when writing text is invisible when renaming nodes on BSPWM, as far as i can tell this is the only place where it happens as otherwise, on node properties or filesystem, its fine

### Steps to reproduce

rename any node on BSPWM

### Minimal reproduction project (MRP)

N/A

Start by reproducing node renaming on BSPWM with the reported Godot versions and compare the text cursor with node properties and the filesystem dock. Trace the editor path used for node-name editing and verify the cursor becomes visible there without regressing the other editor fields.
