--- Comment #3 from Mike FABIAN  ---
There are two ways to use the Sinhala Wijesekera keyboard through ibus:

1) using ibus-m17n (m17n:si:wijesekera)
2) using ibus-typing-booster

You are using 1), but I also tested 2) and compared.

My test results are as follows:

Gnome-Xorg:
    m17n:si:wijesekera: (It makes no difference whether use-surrounding-text is
0 or 1)
        gedit: OK
        libreoffice (writer): OK
        gnome-terminal: OK (bad rendering, but input works OK)
        emacs: WRONG.
        xterm: WRONG, exactly the same way as in emacs
    typing-booster, si-wijesekera input method:
        gedit: OK
        libreoffice (writer): OK
        gnome-terminal: OK
        emacs: OK
        xterm: OK
Gnome-Wayland:
    m17n:si:wijesekera:
        gedit: OK
        libreoffice (writer): OK
        gnome-terminal: OK
        emacs:WRONG
        xterm: WRONG, exactly the same way as in emacs
    typing-booster, si-wijesekera input method:
        gedit: OK
        libreoffice (writer): OK
        gnome-terminal: OK
        emacs: OK
        xterm: OK
KDE Plasma:
    m17n:si:wijesekera:
        gedit: OK
        libreoffice (writer): OK
        gnome-terminal: OK
        konsole: OK
        kate: OK
        emacs: WRONG
        xterm: WRONG
    typing-booster, si-wijesekera input method:
        gedit: OK
        libreoffice (writer): OK
        gnome-terminal: OK
        konsole: OK
        kate: OK
        emacs: OK
        xterm: OK

(Of course the terminals cannot display Sinhala well, but
I can still test whether the input works by typing
    echo '' > /tmp/test
into the terminal, then type the Sinhala between the '' and the return,
then look at the contents of the /tmp/test file for example with gedit)

According to my tests, the desktop does not seem to make a difference.
Sinhala input into programs using XIM like emacs or xterm fails,
it fails in exactly the same way for emacs and xterm, I think it
fails in the same way for all programs using XIM.

Programs using ibus-input modules like gedit, libreoffice,
gnome-terminal, konsole, kate, seem to work fine.

What is different between your tests and mine is that for me
libreoffice works, for you it does *not* work. I don’t understand why,
I used a Fedora 29 installation in qemu with all current updates for
testing.

And what is a bit surprising that using si-wijesekera through
ibus-typing-booster
*always* works for me, in all programs, even those using XIM like emacs and
xterm.

So using si-wijesekera through ibus-typing-booster might be a workaround
for you until we figure out what the problem with ibus-m17n is.
