In my WKWebView controller, I use:
[i_webView.configuration.userContentController addScriptMessageHandler:self name:@"KeyboardMaestro"];
This creates a reference to the controller (self). The controller will not be dealloc'ed when the window is closed.
If in the willClose method I do:
[strongSelf1->i_webView.configuration.userContentController removeScriptMessageHandlerForName:@"KeyboardMaestro"];
The controller will dealloc normally.
However, if I instead fo:
[strongSelf1->i_webView.configuration.userContentController removeAllScriptMessageHandlers];
The controller does not dealloc, so a reference is retained.
Since removeAllScriptMessageHandlers should cover the case of removeScriptMessageHandlerForName:@"KeyboardMaestro" and more, this seems to be a bug.
