eM Client Ignores Reply-To when From and To are my own address

In eM Client (10.4.5674 (fcbf2a4)), clicking Reply on a website contact-form email selects my own address instead of the customer’s Reply-To address.

Using placeholder addresses, the received message headers are:

From: Website <[email protected]>
To: [email protected]
Reply-To: [email protected]

Expected: Reply addresses [email protected].

Actual: Reply addresses [email protected].

Gmail correctly addresses [email protected] when replying to the same message. I verified that the Reply-To header is present in eM Client’s View Mail Header window.

Is there a setting to honour Reply-To in this situation, or is this a known issue?
