WKWebView Certificate Authentication Not Working

Hi,

We want to load a certificate based SAML login request in WKWebView with websiteDataStore as nonPersistent and its not working as expected. The certificate credentials is getting rejected and lands in login form page. When we change the websiteDataStore to defaultStore() client certificate authentication works but we are getting incorrect cookies I have raised this issue here https://feedbackassistant.apple.com/feedback/7799198. Please find the attachment of sample project currently its a blocker for us we are having 2 issues if any 1 is solved it will great for us to proceed further.

Thanks, Vinoth
