Thank you for suggesting a way to access message headers.
I tried to force focus directly from the event_loseFocus() method, but it's a bad solution... and it didn't work.

For some discussion regarding similar issue please take a look at:
https://github.com/nvaccess/nvda/issues/5960

Also Derek Riemer did something similar in his Notepad++ add-on. This is
not in the code since Npp was changing too rapidly breaking the fix with
every update, but for a sample implementation you can take a look at:
