* Fix task-list checkbox styling The pandoc renderer will append the class "task-list" to the ul element wrapping a li with one or more check-boxes. This allows us to select for them, removing their list-style-type property. However, goldmark and the gfm spec doesn't specify the "task-list" class name, so we can't use that to fix the issue there. Signed-off-by: Alexander Scheel <alexander.m.scheel@gmail.com> * Update to goldmark v1.1.25 This version adds the missing space after a checkbox. Resolves: #9656 Signed-off-by: Alexander Scheel <alexander.m.scheel@gmail.com> Co-authored-by: zeripath <art27@cantab.net>
