Subject: [PATCH] [FIX] web: allow the usage of .at in lower versions of Safari

Commit [1] refactored the mail code and introduced a few .at called on
Array typed objects. This is not supported in lower versions of iOS
which some of our users and visitors still use as shown by [2].

This commit introduces a polyfill to support the feature on Safari
<=15.3.
