The IME implementation has been entirely community contributed, so someone from the community will need to debug this.

PR for this would be welcome.

You'll need to create an issue at https://github.com/chromiumembedded/cef/issues for this.

It might need fixing in CEF first, someone will need to investigate to determine.
