Autocompletion problem

[Sebastian Di Mateo]

Hello, everyone.
I'm on 2.6.18 running on Fedora 27. I'm experiencing the same problem as
described here:
https://lists.gnucash.org/pipermail/gnucash-user/2011-July/040365.html
Autocompletion of account names tends to assume I want to pick the first
option that is highlighted, usually when typing fast. The message I link to
said the problem was reported and intended to be solved sometimes on 2.4
versions but I'm still experiencing it.
Any clues?
