I'm using multiple instances of WKWebView in my document-based application, as preview windows and to display some data etc.
The views are set to nil when documents are closed, I'm removing their messageHandler instances and everything works fine, but Instruments and Xcode keep complaining that multiple instances of WKWebViewDataStore get leaked.
It's impossible to null the datastore, and I don't use it at all anyway. I have no idea how it gets leaked, or if it's just a bug in WKWebView. Where should I start debugging the problem?
