Wagtail QA: Bullet points

[alanmoo]

From @kristinashu in #1325

• Spacing after bullet points should be the same or larger than before them
  Screen cap from production looks confusing because bullets look grouped with content bellow, not above

[Pomax]

The reason this is going wrong is because the structure her is:

<p> Bylaws [...]</p>
<ul>
   [ list elements]
</ul>
<p>Conflict [...] </p>

and paragraphs have uneven margins. Our CSS sets this:

p {
  margin-top: 0;
  margin-bottom: 1rem; }

and so the real problem is the paragraph below the ul "glueing" itself to the content above it.

This rule seems to come from bootstrap-reboot.css so we might be missing our own override here.
