How do I extend the list of allowed propertis on HTMLElements?

[SalBakraa]

I am using the svelte-preprocess-delegate-events and it has a section detailing how to integrate the preprocessor with svelte-check. I was wondering if there was a way to do the same with the svelte language server so that the error below stops showing up? The error only shows up in the language server.

Argument of type '{ class: string; type: "reset" | "submit" | "button" | null | undefined; "on:*": undefined; }' is not assignable to parameter of type 'HTMLProps<"button", HTMLAttributes<any>>'.
     Object literal may only specify known properties, and '"on:*"' does not exist in type 'HTMLProps<"button", HTMLAttributes<any>>'. [2345]

I don't know if this is the correct place to ask this, but the svelte/lang-tools repo doesn't have a place for discussion.
