Svelte confused when handling component-event, using same #each-alias for different arrays, and replacing item in array

[aphitiel]

Sorry for the crappy title, guess it's an edge-case;)

I have two lists using the same component. The component fires an event that invokes a method, passing the current item from the list. This method replaces an item in the list.

At the next click it gets passed the old item, if

• there are 2 #eaches
• both use the same alias
• the method gets invoked from a component
• the array-item gets replaced, not mutated

Here's a REPL that's hopefully a bit more understandable.

good news, I've just checked this against #1173 and it looks like it's already fixed!

Confirmation that this works in 1.56: https://svelte.technology/repl?version=1.56.0&gist=4b3699547365bd2dd432d3f70929553d. Thanks!
