I've a feeling that support for m17n has been downgraded, so that it
isn't part of the basic installation.

In short, I think you may also need to install package ibus-m17n.

You've half-reported the distribution - I'm not sure what 'fresh Ubuntu
22' means.  I'm currently relying heavily on m17n with ibus as I
mostly use Kesmanee-based layouts for Indic scripts, and mostly
successfully use it, and I have:

OS, from uname -srv: Linux 6.2.0-39-generic #40~22.04.1-Ubuntu SMP
PREEMPT_DYNAMIC Thu Nov 16 10:53:04 UTC 2
(uname -a gives more information.  uname -o calls the operating system
GNY/Linux.)

Distribution (PRETTY_NAME from /etc/os-release): Ubuntu 22.04.3 LTS

Ibus (selection from 'dpkg -l 'ibus*'):
 
ibus: 1.5.26-4 (status ii)
ibus-m17n: 1.4.9-1 (status ii)

m17n (from 'dpkg -l 'm17n'):
m17n-contrib: none (status un)
m17n-db: 1.8.0-3 (status ii)
m17n-doc: none (status un)

ii means successfully installed.
un means 'unknown' and not installed.

If installing ibus-m17n doesn't solve the problem, let us know what
ibus packages you have *installed*.  The command dpkg -l 'ibus*' | grep
ii' on my machine yields, modulo white space:

ii ibus            1.5.26-4 amd64 Intelligent Input Bus - core

ii ibus-data       1.5.26-4  all  Intelligent Input Bus - data files

ii ibus-gtk:amd64  1.5.26-4 amd64 Intelligent Input Bus - GTK2 support

ii ibus-gtk3:amd64 1.5.26-4 amd64 Intelligent Input Bus - GTK3 support

ii ibus-gtk4:amd64 1.5.26-4 amd64 Intelligent Input Bus - GTK4 support

ii ibus-m17n       1.4.9-1  amd64 m17n engine for IBus

ii ibus-table      1.16.7-1  all  table engine for IBus

I do suffer one nasty bug.  I have a keyboard carefully crafted to
deliver precomposed characters, but they're being delivered using NFD,
whereas one of its purposes, that use to be satisfied, was to enable me
to grep NFC files.  Instead, I have to use the Emacs quail equivalents
and run in an Emacs shell, rather than simply running in a handier (but
less capable) GNOME terminal.
