Misformatted Snippet when using a typed instance of a Class

[oliie]

My relevant packages:

{
  "@sveltejs/kit": "^2.3.2"
  "svelte": "5.0.0-next.246",
  "prettier": "^3.3.3",
  "prettier-plugin-svelte": "^3.2.6",
}

When I have made a Snippet with typed arguments using an instance of a Class, the formatting fails and breaks the code.

Example before format:

{#snippet priceListItemsTabContent(title: string, tableInstance: InstanceType<new () => TableHandler<PriceListItem, PriceListItem>>, entityStatus: string)}

After format:

{#snippet priceListItemsTabContent(title: string, tableInstance: InstanceType<new ()}

This causes the code after to break. I've also noticed it sometimes created duplicated rows of code, but I cant provide an example for that.

I could solve it however by adding line breaks OR extracting the type to the script, causing the formatting to be fine.

Example 1 solution

{#snippet priceListItemsTabContent(
  title: string,
  tableInstance: InstanceType<new () => TableHandler<PriceListItem, PriceListItem>>,
  entityStatus: string
)}

Example 2 solution

<script lang="ts">
  type TableHandlerPriceListItem = InstanceType<new () => TableHandler<PriceListItem, PriceListItem>>;
  // ...
</script>

{#snippet priceListItemsTabContent(
    title: string,
    tableInstance: TableHandlerPriceListItem,
    entityStatus: string
)}

<!-- or as one line -->

{#snippet priceListItemsTabContent(title: string, tableInstance: TableHandlerPriceListItem, entityStatus: string)}
