@andy-goryachev-oracle The behavior you're seeing when clicking on another control is a manifestation of https://bugs.openjdk.org/browse/JDK-8320912. I put together a fix for that bug but decided not to roll it into this PR. If it would help testing I could do that.

The current code to disable the IME happens *after* focus has already moved to the node that doesn't want IME input. So the commit that's fired off by `unmarkText` targets the wrong node. The fix is to implement finishInputMethodComposition so we do the cleanup before the focus changes.
