The call to `_subscription.Dispose()` causes `BindingEntry.Dispose()` to call `_subscription.Dispose()`, but in this case the `BindingEntry._subscription` instance is the `PropertySetterInstance`!
Except now `PropertySetterInstance._subscription` is null, and so `PropertySetterInstance.Dispose` called `ClearValue`, which is obviously wrong.
Exposed by the previous fix for #8372: re-entrancy in `PropertySetterInstance.Dispose()` is causing detaching a style to call `ClearValue` on the property. Previously this wasn't a problem as `ClearValue` didn't work, but now it is.
(Also added one passing test which tests the same scenario in `PropertySetterBindingInstance` for future coverage)
