on webkit Safari, fixed line-height for li::marker leads to ugly first line spacing in multiline items

[acsr]

In VLT 6.0.0.a15 in regular Volto text blocks with listing ul-list items style the initial line has a different linespacing. Together with missing margin-bottom this looks misleading ugly on Safari both on Desktop and mobile.

• The line height of the list item marker exceeds the regular line-height of 24px and forces a greater line spacing after the first line.

  li::marker {
  line-height: 32px;
  }

  The issue is created by different interpretation of this snippet in Webkit. It does not show off in Chrome:

• There are other ul list examples lacking this effect on the https://2025.ploneconf.org/tickets page
