`enhanced:img` returns `NaN` height when image is imported within script block

Describe the bug

This HTML was generated by enhanced:img with the same source image, but loaded two different ways:

Notice one has a valid height and the second is NaN.

Reproduction

The first (green box) containing the valid height was generated using:

<enhanced:img src="$lib/assets/images/example.png?w=280;560" alt="" width="280"/>

The second (red box) was generated using:

<script lang="ts">
  import example from "$lib/assets/images/example.png?enhanced&w=280;560"
</script>

<enhanced:img src={example} alt="" width="280" />

I assume this is unexpected b/c the property would at least be omitted but never added as NaN.

Additional Information

No response

Reproduce the issue with the two Svelte snippets in the report, comparing the generated image markup for the direct enhanced:img source and the imported ?enhanced source. Done means the imported-image path no longer produces a height of NaN; the report does not name a source file or test to run.
