Balboa theme 2-column masonry gallery

I'm working on a site that uses the Balboa theme.  By default, the masonry gallery jumps from 2 columns to 1 between screen width 768px and 577px.  At 556px it returns to two columns.  I'm can't determine what is causing this jump and how to prevent it cleanly.  The solutions I've found in the link below result in either a reordering of the images or large vertical gaps between images. 

Any ideas for disabling this forced 1-column switch?

Hi,

What is site url? We can check easier

Hi Taunphan,

You can use the Balboa demo site, as the same issue exists there by default.

@media only screen and (max-width: 768px) {
    .gallery-masonry .gallery-masonry-wrapper {
        columns: 2;
        column-gap: 0;
        height: auto!important;
        display: block!important;
        padding: 0px;
    }
    .gallery-masonry-item-wrapper {
        height: auto!important;
    }
    .gallery-masonry-item {
        position: relative!important;
        transform: none!important;
        width: 100%!important;
        display: block;
        padding: 1.5px!important;
        box-sizing: border-box;
    }

    .gallery-masonry .gallery-masonry-item img {
        height: 100%!important;
      	width: 100%!important;
    }
}

Thanks.  This css maintains the two columns, but reorders all of the images.  I'm ideally looking for a fix that doesn't reorder every image or leave massive vertical gaps.
