It also fails on my side.

Yet,
make test EMACS="emacs-26" does _not_ fail.

I tried harder then and found that
make test EMACS="emacs-26" BTEST_RE="test-ol/insert-link-insert-description"
_does_ fail.

I am also puzzled now. Running all the tests works, while running a
single test does not.

In any case, we cannot, unfortunately, use map-do here and should
probably fall back to the previous version with cl-loop.
