Compilation fails when using two bind:this to array/object with same key
Error msg: Variable 'xxx' already initialised with a different value

Bug (version 3.20.1)
https://svelte.dev/repl/5d29d37523c14015b3d79fa53d21e1dd?version=3.20.1

Bug didn't exist in version 3.10.1 (haven't checked other versions tho):
https://svelte.dev/repl/5d29d37523c14015b3d79fa53d21e1dd?version=3.10.1

Note that this bug occurs when there is more than 1 component, if using 1 component it works.

Edit 1:
This bug occurs both when using destruction in each and without using it

I don't think it's a bug. Your variable is already binded to the DOM element corresponding to the first Comp component, so it can't be binded again to another DOM element. Why would you need to bind two elements to the same variable ?

@Oreilles
I created a new REPL showing in some context what I am trying to achieve:

https://svelte.dev/repl/1e2c16c929a64890adeddf7fa9d65fa1?version=3.20.1

When using just one of the <BootstrapToggle /> the code compiles fine

[Oreilles]

Oh, I missed that it was two different arrays items1 and items2 in your first example. Seems like a bug indeed.

The second REPL is far too complicated. This does however look like a bug. Very strange.
