Typing an underscore switches focus from the feature editor to the document

This means you can easily type text accidentally into the document

I've just tried this and can't reproduce it. Is this specific to Mac or Windows?

I tried an underscore in the annotation name, feature name, and feature value and none cause the focus to switch. I also can't see any reason why it should it's not as if underscore is a control key in any sense. I think there must be something else going on here
