Missing infill with 1.8.0 (Maybe related to Ensure Vertical Shell Thickness)

[ShryuKt]

OrcaSlicer Version

1.8.0

OS version

Windows10

Additional system information

No response

Printer

Voron2.4

How to reproduce

The version 1.8.0 create some gap in infill when I Slice a simple model with just a base and some walls.
To the best of my knowledge, I think there is something wrong with the return of "Ensure Vertical Shell Thickness" and it may be related to #2645 and #2716

This is the model slice on 1.7.0

Actual results

And this is the problem :

Same profil : Left 1.8.0 / Right 1.7.0

The gap begin on layer 4

The layer 6 is OK

Expected results

Still not what I expect but at least no gap.
Same thing but with Ensure Vertical shell Thickness on 1.8.0

I tried the build https://github.com/SoftFever/OrcaSlicer/actions/runs/6846552190.
But it seems that the problem is not related to the PR #2716 after all, the gap is still present with this build.
