I now have a reasonably OK workaround as I can use gedit instead of emacs. And Libre Office works fine. Thanks for adding me to other bug reports. I hope they'll get resolved soon.
Clarification: This workaround is satisfactory only after switching to Xorg, and combining with ibus-typing-booster
Initial issues are still there for those who want Fedora (Gnome + Wayland) to support Sinhala input out of the box.
