Responding to a Message Context Menu Interaction with form-data via HTTP Response

[OfficialSirH]

Description

When responding to an interaction (received from HTTP POSTs) specifically of a message context menu interaction with form-data, it will just 'not take it' and fail.

edit: this ain't an "only issue with files" problem, it just fails with form-data no matter what.

Steps to Reproduce

1. Have an HTTP-only application that can handle interactions received from HTTP POSTs
2. Receive a message context menu interaction
3. respond to that interaction via HTTP Response with files
4. profit fail

Expected Behavior

the ability to reply with files via HTTP Response just like the HTTP Request

Current Behavior

doesn't allow files via HTTP Response

I've had the same issue with perfectly valid body and headers, as well as multiple other people in ddevs.
