No, it should not :) This is one of the two central points that should
have been be fixed with the newer Horde. Horde uses a caching system
now which should buffer all the groupware data comparable to the
Kontact client.

If this caching system does not work then access via Horde will be
painfully slow since you will have to fetch and parse *ALL* the mails
in an IMAP folder for each web page access.

But you are right, this has been reported before:

https://www.intevation.de/roundup/kolab/issue2396

Can you add additional details in that bug?

One questions is especially important:

 - Where does Horde try to store the kolab cache data on your system? 

It should be the normal temporary directory defined within Horde.
