Addon types are lost after passing through the handler

[gwsbhqt]

version 2.0.1

import { formUrlAddon } from 'wretch/addons'
import wretch from 'wretch'

export const fetch = wretch()
    .addon(formUrlAddon)
    .defer(w => w)
    .resolve(r => r.json())

export const fetch2 = wretch()
    .addon(formUrlAddon)
    .defer(w => w)
    .addon(formUrlAddon)
    .resolve(r => r.json())

export const fetch3 = wretch()
    .addon(formUrlAddon)
    .defer(w => w)
    .addon(formUrlAddon)
    .resolve(r => r.json())
    .headers({})

export const fetch4 = wretch()
    .addon(formUrlAddon)
    .defer(w => w)
    .addon(formUrlAddon)
    .resolve(r => r.json())
    .addon(formUrlAddon)
    .headers({})

error TS2684: The 'this' context of type 'Wretch<FormUrlAddon, unknown, undefined>' is not assignable to method's 'this' of type 'FormUrlAddon & Wretch<FormUrlAddon, unknown, undefined>'.

	defer<Clear extends boolean = false>(
	this: Self & Wretch<Self, Chain, Resolver>,
	callback: WretchDeferredCallback<Self, Chain, Resolver>,
	clear?: Clear
	): Wretch<Self, Chain, Resolver>

Self & Wretch<Self, Chain, Resolver> -> Wretch<Self, Chain, Resolver>
I found that every handler removes the self type, causes the next handler to fail to get the self type.
Is my understanding wrong?

Hey @gwsbhqt, thanks for reporting the issue! 🙏

On the contrary you're absolutely right, I'm pushing a fix right now and releasing 2.0.2 which should solve the problem.
