Changing email address adds extra character if new address has two characters before the domain name

Logged in to https://zoom.us/profile and changed the email address for a Zoom account.

The new email address is ***********. However, the confirmation email never comes through.

Taking a closer look, it appears Zoom adds an extra character to the new email address which of course means the confirmation email never gets through. The redacted email address on https://zoom.us/profile displays as:

a**@example.com

Normally, the number of asterisks matches the number of characters in the email address.

Can this be investigated and addressed?
