“Reply-To: [email* your-email]” shows “Invalid mailbox syntax” warning

With Contact Form 7 4.8.1, using this line in “Additional Headers”:

Reply-To: [email* your-email]

… results in an “Invalid mailbox syntax is used in the Reply-To field” warning, even though the form itself works fine.

Here’s a screenshot demonstrating the problem: https://ibb.co/hx8gXF

It seems that this is just an omission in the syntax parser, because https://contactform7.com/configuration-errors/invalid-mailbox-syntax/ states that [email* your-email] should be allowed in a Reply-To header.
