Webauthn registrations are lost when clearing Safari cookies/website data

When going to «Settings > Safari > Clear logs and website data» to e.g. clear all cookies than all Webauthn registrations done for all sites with Safari is deleted.

This makes Safari for all websites unusable. All websites still lists e.g. the iPhone as Webauthn enabled, while in reality it has been deleted on the device.
