Can't change icon size with enable_recursive_icon_lookup

[marie-bnl]

Issue description

When enable_recursive_icon_lookup is enabled, the icon size is blocked at 40x40, it's impossible to scale it up (didn't try scaling it down), however when I disable it, it does scale up to 64 (the max icon size) as expected.

Installation info

• Version: 1.8.1 (2022-03-02)
• Install type: pacman -S dunst
• Window manager / Desktop environment: i3

With enable_recursive_icon_lookup

[global]
    enable_recursive_icon_lookup = true
    max_icon_size = 64

Without (expected behaviour)

[global]
    max_icon_size = 64

Note for reproducing: the two configurations below are a whole dunstrc, not just a part of it

Is the icon passed via a whole path or is it part of an icon theme?

The icon is a 600x600 png passed as a full path

notify-send "John Doe" "Lorem ipsum..." -i ~/.face.icon

Can you attach the file for testing?

Of course! Here you go
