Auto-update included themes (esp Feedlish)?

[iophobia]

Since a recent Ttrss commit broke the feed title background in most themes, I was wondering whether the auto-update also pulls the most recent theme. Feedlish already had an update and I'd like to make use of it.
Alternatively, what would be the endpoint for the themes folder, so that I could mount it myself? Thanks in advance.

Edit: My interim solution now was to clone the feedlish git onto my server and mount the folder as /var/www/ttrss/themes.local/gravemind-feedly-git in docker as per your setup-ttrss.sh file

We actually do update the themes as part of the automatic updates already. Does this now work for you?
