I've created a sample project that demonstrates the issue. I've tried to
make it as simple as possible.
When executing the app, There will be a single instance of the compound
component which includes two letters, one over the other. (A/Q) For clarity
sake, the 'A' is Yellow and the 'Q' is gray. Long-press on the 'A' and you
will bring up the soft keyboard. As you select letters from the soft
keyboard, the letter 'A' should change.
My continued thanks for those who are reviewing this.
