ItemList trims item text too much in specific cases

[RodZill4]

Tested versions

• Reproductible in 4.4b2 and 4.4b3
• Not reproductible in 4.4b1 and before

System information

Godot v4.4.beta3 - Windows 11 (build 26100) - Multi-window, 1 monitor - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 2060 (NVIDIA; 32.0.15.6094) - Intel(R) Core(TM) i5-10400F CPU @ 2.90GHz (12 threads)

Issue description

It seems item texts are trimmed way too much in item lists when a fixed icon size is specified, but actual icon textures are bigger.

Here's how it shows in Material Maker's "Add node" popup:

And here's how it should look like (and does look like with beta1):

It seems that enabling the "same_column_width" flag workarounds the problem.

Steps to reproduce

Just open the minimal project in Godot 4.4b3 and the problem is visible in the "2D" view.
