What's the difference between
np.abs(ad_bc) < 1.0e-12np.isclose([0], [ad_bc], atol=1.0e-12)
Why would I prefer the longer over the shorter?

PR Summary
Fixes #11294.
A comparrisson with 0 (
x == 0) is replaced by comparing with a small number (abs(x) < eps) such that numeric errors do not bypass the raising of an error for non-intersecting lines.Related to that, commit #9519 intended to add a test for ConnectionStyles which was hindered by errors as seen in #9518. This PR adds the desired test by choosing an arrow style, which allows for all ConnectionStyles to be tested. Hence fixes #9518.
