Adding an attachment to a mail does not work

[phsc84]

RainLoop version, browser, OS:
1.14.0-djmaze3, Chrome 84.0.4147.125 (64-Bit), Windows 10 Home 1903

Expected behavior and actual behavior:
In the window to compose a new mail, an attachment could be added via drag&drop in the original Rainloop 1.14.0. Unfortunately this does not work in the djmaze3 version anymore.
It is also not possible to add an attachment via the file selection button.

Steps to reproduce the problem:
Just try to add an attachment.

Logs or screenshots:
Unfortunately nothing happens. No error pops up. It just does not add the attachment.

Yes, this is fixed in the re-release of djmaze3 tar.gz and zip.
@h3artbl33d already reported it to me.
The problem was my incorrect replacement of $.ajax to FormData.
