On the "Select source" screen of new Application wizard, when user enters errorneous URL (for example `https://my.test/test`), SPIAccessCheck correctly recognizes this URL is wrong (or this provider has not been implemented), but the UI is still showing `Validating...` indefinately.

Spec and Status of corresponding SPIAccessCheck:
