[Linux] Keyboard input doesn't work with iBus running

[lookingafar]

If installed through Snap and with iBus running the keyboard doesn't work in Standard Notes desktop app (and some other snap apps) on Manjaro 21.1. Killing iBus solves the problem. This means, however, that there is no way to use the app to enter Chinese or Japanese characters with iBus.

The keyboard does, however, work in Visual Studio installed through snap, so I am not sure whether this is a snap problem or it has something to do with how Standard Notes interacts with snap.

Here is a related snap bug that, as they state, has been fixed
https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1863255

steps to reproduce:

1. Install Standard Notes through snap with sudo snap install standard-notes
2. Launch ibus by running ibus-daemon
3. Launch standard-notes
4. Keyboard input doesn't work in any field throughout the app except for the password field in the sign-in window.
