Thank you for confirming. Hopefully the issues with core24 will soon be
solved and the stable channel will be able to transition, thereby
closing this bug.

Title:
Chromium looses keystrokes with ibus-engine-keyman
Status in chromium-browser package in Ubuntu:
Confirmed
Bug description:
With Chromium backspaces generated by ibus-engine-keyman get lost.
For apps like Chromium that don't support surrounding text, ibus-
engine-keyman generates a backspace to delete a character from the
context. However, it appears that the version of `im-ibus.so` included
in the gnome-42-2204 snap package is too old and has a bug so that it
appears that Chromium would support surrounding text. Newer ibus
versions have this bug fixed.
Note: to properly work with apps that don't support surrounding text,
the version of ibus-engine-keyman included in the Ubuntu repos (Keyman
17) requires a patched version of ibus that didn't make it to the
Ubuntu repos. It can be installed from
https://launchpad.net/~keymanapp/+archive/ubuntu/keyman.
Alternatively, the upcoming Keyman 18 no longer needs a patched ibus
and can be installed from
https://launchpad.net/~keymanapp/+archive/ubuntu/keyman-beta.
To reproduce:
- install the beta version of Keyman 18 from
https://launchpad.net/~keymanapp/+archive/ubuntu/keyman-beta, or Keyman 17 from
the Ubuntu repos and the patched ibus from
https://launchpad.net/~keymanapp/+archive/ubuntu/keyman
- install the "IPA (SIL)" keyboard from https://keyman.com/keyboards/sil_ipa
by running: `km-package-install -p sil_ipa`
- open Chromium
- switch to the "Undetermined (IPA (SIL))" keyboard
- in a input field in Chromium, type n>
Expected output:
ŋ
Actual outputː
nŋ
(What's happening: after receiving the ">" keypress, ibus-engine-
keyman checks if the app that has the focus supports surrounding text.
If it does, it calls `ibus_engine_delete_surrounding_text` to delete
the "n", otherwise generates a backspace to delete the "n". This is
followed by outputting "ŋ". Since the im-ibus.so available in the
Chromium snap package contains a bug, ibus-engine-keyman gets the
information that Chromium supports surrounding text. However, Chromium
doesn't implement that and so doesn't actually delete the character.
Ibus has already fixed the bug, but that isn't yet available in the
Chromium/gnome-42-2204 snap package)
