csr breaks "a" link elements contained inside an "svg" element

[peufo]

Describe the bug

When client-side rendering is enabled, links inside an Svg component disappear.
Still, no problem if a native svg element is used.

Reproduction

See: https://github.com/peufo/kit-bug-report-link-svg
or

1. Make sure csr is enabled (default)
2. Create a simple SVG component "Svg.svelte"

<svg
  viewBox="0 0 100 100"
  xmlns="http://www.w3.org/2000/svg"
  xmlns:xlink="http://www.w3.org/1999/xlink"
>
  <slot />
</svg>

3. Use it with links inside

<script>
  import Svg from './Svg.svelte'
</script>
<Svg>
  <a href="/42">
    <text x="50" y="90" text-anchor="middle"> test link </text>
  </a>
</Svg>

Seems like a Svelte "bug" instead, see https://svelte.dev/repl/8c9bb576f1f348a3953f391a9e90a27f?version=3.55.0

For the a inside the SVG tag, the compiler identifies it as an SVG anchor and uses svg_element to create it, whereas for the slotted one the compiler has no way of knowing it's inside an SVG so it just creates a normal anchor element which doesn't work the same way

Well seen,

This opened issue already exists in the svelte project, I missed it: /sveltejs/svelte/issues/7807

Thanks for the explanation, I close this one.

@gtm-nayan Mea culpa! Svelte provides a "namespace" option to signal to the compiler the context of a component:

<svelte:options namespace="svg"/>
