[horde] IMP - Error on attachment download

Hello,
Latest IMP 7.0.2 (+ comit ae468ef) still presents the download
problem for attachment files.
Also a new bug about pre-view scrolling. Some erratic problem on
email preview on main IMP window (on a PC using chrome and Firefox, I
do not test others). When the mail is longer than the windows, some
mails do not scroll. For example the mail "Re: [horde] Activesync :
call for testing II" from "<horde-bounces at lists.horde.org>"
Delivery-date: Tue, 07 Jul 2026 17:19:42 +0200 does not scroll on
pre-view.
Sorry, but I cannot give any way to reproduce it. Just a mail
everyone on this list have that shows the error.
Best regards
Angel
