First layer perimeter/infill order - infill of one segment runs before perimeters of other ones

[amra]

Description of the bug

One object has multiple distinct segments on the first layer. Each segment is printed whole (perimeter, infill) before starting another one.

This is an issue, because perimeters have the highest chance to fail on the first layer, and you must wait for the last one to be finished. It's time and material consuming.

On the first layer, I expect to finish perimeters first and then continue with infills, even when the model is divided into multiple segments on the first layer.

Project file & How to reproduce

Print anything from Gridfinity models with more than one base segment.

For example https://www.printables.com/model/293060-gridfinity-bins-height-6-42mm/files#preview
The first layer splits into 20 segments, and you have to wait ages for the last segment perimeter to be printed (and hope not to fail).
