Do HTTPCookieStorage.shared() and WKWebsiteDataStore.default() share cookies?

Question

I have a web view in my app whose cookies are stored automatically in WKWebsiteDataStore.default(). When I logout I delete these cookies using :

[[WKWebsiteDataStore defaultDataStore] fetchDataRecordsOfTypes:WKWebsiteDataStore.allWebsiteDataTypes completionHandler:^(NSArray<WKWebsiteDataRecord *> * _Nonnull records) {
    [[WKWebsiteDataStore defaultDataStore] removeDataOfTypes:WKWebsiteDataStore.allWebsiteDataTypes forDataRecords:records completionHandler:^{}];
}];

But when I login again the WKWebsiteDataStore is having same old cookies. Through iteration I checked that these cookies are stored in HTTPCookieStorage.shared also and WKWebsiteDataStore probably uses them.

I want to know what's the dependency between these two. Should I clear cookies in both WKWebsiteDataStore and HTTPCookieStorage?
