Custom script icons render too small on Retina display

System information

Godot v4.3.stable - macOS 14.6.1 - GLES3 (Compatibility) - Intel(R) UHD Graphics 617 - Intel(R) Core(TM) i5-8210Y CPU @ 1.60GHz (4 Threads)

Issue description

When setting a custom @icon on a script, the icon renders smaller than expected in the Scene Tree. The icon preview in the FileSystem renders at the correct size.

I'm using a MacBook Air with a high DPI / Retina display:

Screen Width: 1440 pixels Screen Height: 900 pixels DPR (Device Pixel Ratio): 2

Steps to reproduce

• Create a new script
• Add a custom @icon pointed at an asset in the FileSystem (.png and .svg both tested)

@icon ("res://assets/icons/icon_save.svg")
extends Node2D
class_name SaveDataResource

• Observe icon in FileSystem pane at incorrect size

Checking "Scale With Editor Scale" in the import tab and then reimporting it should resize the icon to the correct scale.

@detomon Good catch, this does fix the problem for SVG icons! Does lead me to a few additional questions though:

• Should this be checked/true by default? I can't think of any reason why someone would want to use an SVG in the Editor but not scale it to match.
• Should only SVG assets be allowed as custom @icons? Looks like all the built-in icons are SVG and I don't see that Scale With Editor Scale option for importing PNG assets, which leads me to believe the Editor prefers SVG for @icon. And I wouldn't be against the idea of requiring SVG for custom icons, for the sake of simplicity and ensuring accurate rendering.

The documentation doesn't specify a filetype, so at the very least it feels like there's an opportunity for providing clearer user guidance.
