Could I ask that this forced upper case be removed. In keeping with the marvellous general flexibility and user-definable elements of the theme, something like this seems a bit incongruous. If a person wishes their tagline to be all upper case, it is a very simple thing to type it in using all upper-case.
But how can someone who does not wish all upper case cause their tagline to appear in whatever mix of cases they choose? The tagline should simply repeat whatever the user types in.
Not sure if this is a bug or not, but it does seem to be a surprising limitation that might have made sense once but which would benefit from a reconsideration now.
I don't think you need a url to understand the issue, but if you do, here goes
Many thanks
David.
