[BUG] gutterPixels not being applied

[weinde]

Describe the bug
As the title staits, I am experiencing an issue with "gutterPixels" and layout setting... I have tried applying this code but no gutter is visible and my page and grid look broken

    const filterizr = new Filterizr('.filter-container', {
        gutterPixels: 400,
        layout: 'sameWidth',
    });

Filterizr version
"filterizr": "^2.2.4",

Expected behavior
I expected to have three images in a row with 40px of gutter space in masonary layout (sameWidth or packed)... except I get a broken layout with no gutter and images covering one another (2nd screenshot has some padding to images aplied to simulate gutter)
