Odd.  To reproduce, I tried to just do:

(require 'seq)

(defun foo ()
  (with-suppressed-warnings ((obsolete seq-contains))
    (seq-contains '(3 4 5 6) 3)))

But the warning is suppressed correctly then.  So there's ... something
in the way the test files are compile that breaks
with-suppressed-warnings?  Something in the ert macros?  Anybody got any
ideas?
