bug#10409: Minibuffer sized according to default face, not minibuffer face

[David Reitter <david.reitter@gmail.com>]

With further info from Jeremy, it looks like it works as designed.  

So would like to use this bug to request an enhancement (to allow for arbitrary (pixel level) window heights, with minibuffers sized according to the minibuffer face rather than the default face).
