We are migrating a chrome WebExtension. The extension makes API calls from the popup to our domain. We are a subscription service and expect auth-cookie to be sent along with API requests from the extension. Our auth cookies are SameSite=Lax. Chrome and Firefox allow SameSite=Lax cookie to be sent with API calls from the extension, but Safari does not. The expected behavior is: SameSite: Lax cookies should follow the behavior as extension in Chrome and Firefox.
Thanks for filing. For internal tracking this may be related to rdar://64303685.
