After the signout the login page shows the already loged out user email instead of email input field which is something login funciton relies on
this is how the login page is showen when cache is cleared

this is how the login page on re-login and the email locator is missing

Solution

Thanks for the contribution. E2E tests are failing, however. Have you thoroughly tested this?
