I don't understand why you consider it a bug.  According to the doc
string (see below), this:

  (format-spec "%>15t" '((?t . "0123456789")))

should behave the same as this:

  (format "%15s" "0123456789")

And in my testing, it does: both produce "     0123456789".

So I don't think I agree that there's a bug here to begin with.  The
doc string of format-spec says:

  The width and truncation modifiers behave like the corresponding
  ones in ‘format’ when applied to %s.
