Lemmy notifications shown multiple times, once per each open tab

Currently, I get one copy of each notification from 'here' (where I happen to have this account) for each tab under https://lemmy.dbzer0.com/ that I have opened.

This is a major inconvenience; and - I guess - at this time a not-yet implemented feature.

Beyond the issue tracker (or a PR), is there a forum/community (on Lemmy...?) to discuss such enhancements / dev/programming of and around Lemmy?
