Markdown nested list renders flat [solved]

Markdown nested list renders flat.
What is might be problem ?

Tried chaning all kinds of settings…
Using Cocoa theme, AFAIk theme can’t affect this…

  taskLists = true
  angledQuotes = true
  fractions = true
  plainIDAnchors = true
  tabSizeDefault = 4
  extensions = ["hardLineBreak", "tables", "noEmptyLineBeforeBlock", "definitionLists"]

Cocoa theme issue.
After using CSS reset default list appearance is lost. Have to specify manually:

section.main .content .markdown ul {
  margin-top: 0.25rem;
  margin-bottom: 0.25rem;
  padding-left: 1em;

section.main .content .markdown ol > li {
  list-style-type: decimal;

section.main .content .markdown li {
  list-style-type: disc;
  list-style-position: inside;

section.main .content .markdown ul > li > ul > li {
  list-style-type: circle;

section.main .content .markdown ul > li > ul > li > ul > li {
  list-style-type: square;

As an aside, seethe following issue with Blackfriday mentioned in the new docs concept:
