Memory leak problem of ImageRequest.context

[cwh-github]

Android 14

Coil 2.0.0

Code:

fun showImage(imgUrl: String) { 
        val imageViewTarget = object : ImageViewTarget(imageView) {
            override fun onSuccess(result: Drawable) {
                super.onSuccess(result)
               //do something....
            }

            override fun onError(error: Drawable?) {
                super.onError(error)
                //do something
            }
        }
        val imgReq = ImageRequest.Builder(imageView.context).data(imgUrl).target(imageViewTarget).build()
        imageView.context.imageLoader.enqueue(imgReq)
    }

Please update to the latest 2.5.0 where this should be fixed. There's a test here to ensure ImageLoader references aren't held by the network callbacks.
