Awkward scaling of icons

[Nakamerica]

Describe the bug
In GNOME Shell, the wifi and volume icons especially look quite weird with the icon theme applied. On my previous display configuration (2560x1440p scaled at 125%) they looked fine, but on downscaling the display to 1920x1080p at 100%, the two icons looked out of place.

To Reproduce
Steps to reproduce the behaviour:

1. Apply any variant of the Colloid icon pack.

Expected behaviour
Expected look (at 2560x1440p@125%):

how it looks (at 1920x1080p@100%):

As you can see, the wifi and volume icons in the second screenshot look almost too small compared to the neighbouring icons.

Desktop (please complete the following information):

• OS: Fedora 39

On further investigation it looks like the same issue exists on WhiteSur Icons as well.
