Well, it was me who suggested that. Maybe I should rather have pointed
to the rather old bug #1423890, which includes a link to a mailing list
discussion.

@Jamie: The code, which changes the abstract socket path from
'unix:tmpdir=/tmp/ibus' to 'unix:tmpdir=$XDG_CACHE_HOME/ibus', was
uploaded to focal via ibus 1.5.21-5ubuntu1 (unix-socket-path.patch).

[Bug 1856738] Re: access always denied when using @{HOME} tunable in peer_addr for abstract socket
This is due to how the VAR is expanded
assuming
@{HOME}=/home/*/
then
@@{HOME}/.cache/ibus/dbus-*"
expands to
/home/*//.cache/ibus/dbus-*"
and currently the secondary pass to cleanup // is not being done because the
code is treating addr as a profile name where // is a hierarchy separator. We
can treat addr as a pathname so that the cleanup pass is done.
Long term we should make variable expansion smarter so that trailing /
in a var can not result in a // in the expansion.
