Email-to-Case address always gets added as CC address for replies

Email-to-case routing address is almost always in the CC field when sending an email to case. The potential reason for issue:

• Email-to-Case verified routing address stored in DB contains ZWNBSP hidden character
• Upon Email-to-Case creation/loading of previous email we attempt to match the address to a validated from address.
• As the inbound email to an email-to-case routing address is not equal to the email-to-case routing address with ZWNBSP hidden character, the Quick Action defaults the From Address and populated the CC with the sender for the reply email.

NOTE: Most likely when they originally created the Email-to-Case routing address they copy/pasted the email value from another source resulting in it containing this hidden character.
