Bug description

There is a problem when using "grid" without specifying the height of "swiper". The height of each ".swiper-slide" is calculated as a percentage of the total height of the ".swiper-wrapper". And the script does not count the total height of the ".swiper-wrapper".
Because of this, all items are shown in one column.

  const swiperReasons = new Swiper('.swiper-reasons', {
    loop: false,
    grabcursor: true,
    spaceBetween: 0,
    breakpoints: {
        260: {
            slidesPerView: 1,
            loop: true,
            grid: {
                rows: 2,
                },

        },
        768: {
            slidesPerView: 2,
            grid: {
                rows: 4,
                },

        },
    },

  // Navigation arrows
  navigation: {
    nextEl: '.swiper-reasons-btn-next',
    prevEl: '.swiper-reasons-btn-prev',
  },
});

Same here. Using { grid: { fill: 'row' } } works better, but is sometimes not preferable.. This also defeats the purpose of the rows count, when in column mode it is simply ignored

I have the same problem. I want a grid of 4 slides in vertical and in row, it doesn't order them well and in column I can't know the total height as they are slides with variable height. 😢
