Regression @1.56: Click-handler inside #each with array-literal

[aphitiel]

This

{{#each [1,2,3] as i}}
	<button on:click="console.log(i)">{{i}}</button>
{{/each}}

worked in 1.55.1. After that, clicking a button throws

Uncaught TypeError: Cannot read property '1' of undefined
at HTMLButtonElement.click_handler

because this._svelte.each_value is undefined.

REPL:

• 1.55.1 works
• 1.56.0 broken

Looks like it might be a dupe of #1206

Oops, right, sorry!
