I don't know about ungoogled-chromium, but for IceCat, I had
investigated the problem at length in https://issues.guix.gnu.org/59368,
and it seems the bug is not in ICU but in Firefox, triggered in very
specific situations (resistFingerprinting defaults to true before user
prefs are loaded, and resetting the timezone fails in some javascript
that expects /etc/localtime to be a symlink, see:
https://bugzilla.mozilla.org/show_bug.cgi?id=1817004#c8).
