Spinbox display does not round properly when using decimal custom arrow steps

Tested versions

• Reproducible in: v4.2.2 stable, v4.3 stable

System information

Godot v4.3.stable - macOS 15.0.0 - GLES3 (Compatibility) - AMD Radeon Pro 5300M OpenGL Engine - Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz (12 Threads)

Issue description

Using a 0 step value and a decimal custom arrow step on a spinbox causes the displayed value in the spinbox to round incorrectly at some numbers, despite the internal value being rounded. I'm fairly sure this was working previously on both 4.2.2 and 4.3, so its possible its due to me upgrading to the newest macOS. Also reproduced with arrow steps like 0.2, 0.9, and 1.1, and in brand-new project.

Steps to reproduce

Create a new spinbox node, set its step value to 0 and its custom arrow step to a decimal value besides 0.5. Interacting with the arrows results in the issue

There's seems to be some disagreement between what's displayed in the remote tab and what's printed in other parts of my project, but I haven't picked up on anything consistent. I wonder if it's possible that there's some general float rounding issues around the engine in macOS 15.0?
