Description

When i use dynamic images in Vue 3 / Vite project

<Splide :options="spliderOptions" aria-label="Providers">
    <SplideSlide v-for="provider in casinoStore.providers.value" :key="provider.id">
      <div class="provider" :title="provider.name" @click="filterByProvider(provider)">
        <img
          :data-splide-lazy="`/assets/images/providers/${provider.slug}.png`"
          class="image"
        >
      </div>
    </SplideSlide>
  </Splide>

all data-splide-lazy attributes are converted to src on the mount

With

data-splide-lazy="/assets/images/providers/someImg.png"

lazy-loading works fine

I think this bug is important, because causes to forze the browser to load ALL big images of the gallery at same time.
