[Pkg-mailman-hackers] Bug#983895: mailman3-web: After upgrading, dropdown menus don't work.

[peterc at lists.sel4.systems]

Package: mailman3-web
Version: 0+20200530-1
Severity: important

Dear Maintainer,

I had a working mailman3 3.2.2.  I did 
   'apt upgrade'
which installed mailman3 3.3.1 and a new version of mailman3-web,
hyperkitty and postorius.  Now the dropdown menus in the web interface
do not work: clicking on my 'username' at the top right does not 
drop down a menu.  Clicking 'Filter by Role' in the list view does not 
drop down a menu.  

My guess is that something in the upgrade process means there's stale
CSS or stale javascript in the paths served by Django.

The result is that the web interface is almost unusable.
