            Bug ID: 147635
           Summary: WKWebsiteDataStore does not always clear cookies
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified

            Status: NEW
          Severity: Normal

WKWebsiteDataStore does not clear cookies in the following scenarios:
1) WKWebView has been just created
2) There is no WKWebView attached to the WKWebViewConfiguration

(there maybe more scenarios, these are the known ones)


Sample code to run:

WKWebViewConfiguration* config = [[WKWebViewConfiguration alloc] init];
  self.webView =
      [[WKWebView alloc] initWithFrame:CGRectZero configuration:config];

  [self.view addSubview:self.webView];

  NSString* url = @"http://google.com";
  [self.webView loadRequest:
      [NSURLRequest requestWithURL:[NSURL URLWithString:url]]];

// Trigger clearing of cookies.
 [self.webView.configuration.websiteDataStore removeDataOfTypes:[NSSet setWithObject:WKWebsiteDataTypeCookies]
                                                     modifiedSince:[NSDate distantPast] completionHandler:^{
                                                       // Notice that this is not called.
                                                       NSLog(@"Cleared cookies");
                                                     }];

Expected Results:
The completion handler is called and cookies are cleared.

Actual Results:
The completion handler is not called and cookies are not cleared.
