Confirmed.  And the hangs seem to be caused by tests asking for input.

I executed one of these failing tests interactively
(lisp/abbrev-tests.el), and it kept prompting in the minibuffer
where the usual

  (cl-letf (((symbol-function 'read-string) (lambda (&rest _) "<value>")))

should have inhibited that.  Full output of that interactive test to
follow:

Selector: t
Passed:  18
Failed:  3 (3 unexpected)
Skipped: 1
