Bug description

Preconditions:

Initial slide at index 0
lazyPreloadPrevNext > 0

grid: {
    rows: > 1,
    fill: "row"
}

LazyPreloadPrevNext is preloading slides as if there where contiguous instead of taking in account the grid layout.

Expected Behavior

It should remove loading=lazy from the correct slides.

Actual Behavior

It remove loading=lazy removed from the wrong slides (contiguous slides).
