Thanks for the recipe for reproduction.

Yes, I also see this behaviour, and it does indeed behave as documented
(i.e., case is ignored).

But as you say, that's perhaps not optimal behaviour -- in other cases
like this in Emacs (like isearch), Emacs stops ignoring case if the user
enters some upper case characters, and that would make sense here too?

Anybody have opinions here?
