updateMediaBasedOnVariant() {

    );

    const options = this.currentVariant.options.map((option) =>

    );

    const mediaWrapper = Array.from(

      mediaGallery.querySelectorAll(".product__media-item")

    );

    const mediaThumbnailWrapper = mediaGallery.querySelectorAll(

      ".thumbnail-list__item"

    );

    const mediaModal = document.querySelectorAll(

      ".product-media-modal__content img"

    );

    // Set the thumbnail display by default

    mediaThumbnailWrapper.forEach((media) => {

      media.removeAttribute('data-matched');

    });

    // Set the media modal display by default

    mediaModal.forEach((media) => {

      media.removeAttribute('data-matched');

    });

    const matchesMedia = mediaWrapper.filter((media) => {

      media.removeAttribute('data-matched');

      const alt = media.getAttribute("data-media-alt");

      const isMatch = alt === "all" || this.currentVariant.options[0] === alt;

      if (isMatch) {

        const mediaId = media.getAttribute("data-media-id");

        const id = mediaId.split("-").pop();

        media.setAttribute("data-matched", true); media.setAttribute("data-matched", true); Media.

        const thumbnail = mediaGallery.querySelector(

          `[data-target="${mediaId}"]`

        );

        thumbnail && (thumbnail.style.display = "block");

        thumbnail && thumbnail.setAttribute("data-matched", true);

        const modal = document.querySelector(

          `.product-media-modal__content img[data-media-id="${id}"]`

        );

        modal && (modal.setAttribute("data-matched", true));

      }

      return isMatch.

    });

    customElements.whenDefined("media-gallery").then(() => {

      mediaGallery.setActiveMedia(

        matchesMedia[0].getAttribute("data-media-id"),

        true

      );

    });

    // Reset the slider

    customElements.whenDefined("slider-component").then(() => {
