Scenario as follows: An email address is added to my account due to me clicking on an invitation "accept" link in an email (btw, this is annoying, a "accept invite but do not add address"-option would be nice) I go to the email address management page The new address (say, email@example.com) is displayed first, the old address (say, firstname.lastname@example.org) second. I click the delete button next to the new address (email@example.com) The second address disappears from the list, so the list now only contains firstname.lastname@example.org After reloading the page, the list contains only email@example.com as one would expect.
The bug also occurs when manually adding email addresses. The bug only occurs when deleting the first of two email addresses in the list. I did not try with more than two addresses.
