How to do chained transformations in ImageKit? global modifiers in config prevent raw transformation working correctly.

The relevant part of my nuxt.config.ts:

  image: {
    densities: [1, 2],
    provider: 'imagekit',
    // Options see https://v1.image.nuxtjs.org/get-started/
    imagekit: {
      baseURL: 'https://ik.imagekit.io/aicosmetic',
      modifiers: {
        dpr: 'auto' //<-- Note this line - it'll be important later
      }
    }
  },

In my component, I'm trying to load a watermarked image like so, using the raw parameters as per the documentation

              <nuxt-img
                v-if="preview.image"
                :src="preview.image"
                class="m-auto w-full"
                :modifiers="{
                     raw: "l-image,i-36cc1e3c-cb82-4fa6-8b7b-6b5b39394920@@Ruso1,lfo-bottom_right,w-bw_mul_0.4,l-end"
                  }"
              />

The Problem - however - is that when I load up the resulting URL, I get an "invalid transformation" error. This is because I need to chain the dpr-auto before or after the raw modifier with the layer overlay

This is the generated, broken link (note the comma after the dpr-auto: view image https://ik.imagekit.io/aicosmetic/166edd60-1ddc-4911-ac0b-2312c8b2a165/1936-preview-818165818247-2024-07-02_01_07_44.727525-0-final_4up-kGp1G?tr=dpr-auto,l-image,i-36cc1e3c-cb82-4fa6-8b7b-6b5b39394920@@Ruso1,lfo-bottom_right,w-bw_mul_0.4,l-end

When updating the URL manually to chain the layer (with a semicolon) instead of the comma, then we get the right image: view image https://ik.imagekit.io/aicosmetic/166edd60-1ddc-4911-ac0b-2312c8b2a165/1936-preview-818165818247-2024-07-02_01_07_44.727525-0-final_4up-kGp1G?tr=dpr-auto:l-image,i-36cc1e3c-cb82-4fa6-8b7b-6b5b39394920@@Ruso1,lfo-bottom_right,w-bw_mul_0.4,l-end

So, is this a bug or a lack of a feature where config and raw modifiers don't play nice together. or is it a PEBKAC situation?

Any help is much appreciated, thank you for all your work.
