If the same URL is read into the View, the RequestListener will be reused as stale.

## As of Glide 4.16.0, stale instances of RequestListener are reused.

It is common to load images into a single ImageView with Glide. A new RequestListener should be used for each call to Glide, even if it is the same URL.

Up until Glide 4.15.1, newly created listeners are called, but starting in 4.16.0, old listener instances are called.

```kotlin
private fun loadImage(url: String) {
val listener = object : RequestListener {
override fun onLoadFailed(
e: GlideException?,
model: Any?,
target: Target,
isFirstResource: Boolean
): Boolean {
Log.d("TAG", "[onLoadFailed] = ${hashCode()}")
return false
}

override fun onResourceReady(
resource: Drawable,
model: Any,
target: Target,
dataSource: DataSource,
isFirstResource: Boolean
): Boolean {
Log.d("TAG", "[onResourceReady] = ${hashCode()}")
return false
}
}

Log.d("TAG", "[Listener] = ${listener.hashCode()} ==> $url")

Glide.with(binding.imgView)
.load(url)
.centerCrop()
.addListener(listener)
.into(binding.imgView)
}
```
