When I leave the Password AutoFill settings checked and uncheck Password Provider (orion keychain), the keychain autofill icon still appears in relevant fields. The only reason I noticed this issue was because I wanted to disable the keychain autofill and use 1password. I had to check Use Orion's Keychain and uncheck the other four checkboxes before unchecking Use Orion's Keychain again to get the keychain autofill icon in fields to go away.
As I understand the explanatory label under "Use Orion's Keychain", this toggle does not disable AutoFill, but only toggles which keychain is used. However unchecking the option disables the checkboxes below, locking them in whatever their last state was ("Offer to AutoFill", "Use Touch ID", etc).
The "Password AutoFill" checkboxes should remain enabled regardless of the state of the "Password Provider" checkbox.

If this does ever get picked up again, I hope you're able to stick with GTK and webkit.
