Outline Numbering OK in Preview But Heading 3, 4 Not Honoured in Export as PDF

I have an outline decimal heading numbering schema applied via CSS. Workd perfectly in Preview. On File | Export as PDF it fails to increment at heading levels 3 and 4 (I haven't tried any lower than this).

For some reason when exported as a PDF the counters for heading levels 3 and 4 aren't incremented and remain at 1.

Any ideas on what is causing this?

   This is a known issue that's been a headache for a while now. I haven't
   been able to determine why the CSS counters fail to increment in print
   media (including PDF) with the same markup as the display version. While
   I'm still looking into this, I do not have a workaround at the present
   time.

   I'll test further with the provided document. Could you also include the
   configuration details provided by Help->Report an Issue?

   In Preferences->General, do you have Headlines Collapse Sections
   enabled, or disabled?

   Thanks,

   Oh, and are you applying your own decimal outline, or using the Outline
   Mode->Decimal that's built into Marked? If you're applying your own,
   I'll need you to provide your custom CSS for that as well.

   Under Preview I've got 'Headlines collapse sections' enabled

   My own:

   /* heading numbering - decimal outline
   https://www.w3schools.com/css/css_counters.asp */
   body {
       counter-reset: L1;
   }

   h1.nocount:before{
       content:"";
       counter-reset: L1;
   }

   h1:before {
       content: counter(L1) ". ";
       counter-increment: L1; /* add 1 to level 1 heading */
   }
   h1 {
       counter-reset: L2; /* set level 2 heading to 0 */
   }

   h2:before {
       content: counter(L1) "." counter(L2) " ";
       counter-increment: L2; /* add 1 to level 2 heading */
   }
   h2 {
       counter-reset: L3; /* set level 3 heading to 0 */
   }

   h3:before {
       content: counter(L1) "." counter(L2) "." counter(L3) " ";
       counter-increment: L3; /* add 1 to level 3 heading */
   }
   h3 {
       counter-reset: L4; /* set level 4 heading to 0 */
   }

   h4:before {
       content: counter(L1) "." counter(L2) "." counter(L3) "." counter(L4) " ";
       counter-increment: L4; /* add 1 to level 4 heading */
   }
   h4 {
       counter-reset: L5; /* set level 5 heading to 0 */
   }

   which works fine in Preview.

   If you disable Headers Collapse Sections does the problem go away?

   I'm ahead of you - unfortunately, no.

   Ok, you're running into the unsolved bug from before (which exists
   somewhere on this forum, I'd have to search for it). It's a true
   mystery, especially considering that the built-in outline format, which
   uses the same concept, exports fine. I'll look further into it, but at
   this time I have no solution. I know that's a drag, I'm truly sorry I
   haven't been able to solve this one yet.

   OK

   The reason I went down this route is because the standard decimal outline offered by the gear whee; numbers not only headings but paragraphs and bulleted lists - I wanted just an outline structure applied to headings only. As a work-around is this possible to implement via the gear wheel outline method?

    What's weird is that the built-in outlining just uses a more complex
    version of the same method (to account for paragraph and list item
    numbering as well as headlines). It would be futile for me to implement
    your setup on my end, as there's no combination that would cover
    everyone's desires for headline numbering. I just need to figure out why
    the counter increments for my version, but not for a manual override
    version.

    I wonder if using some !important rules on the counter-increments your
    custom CSS might make a difference. I'll explore it, but feel free to
    test on your end if you have the time.

    I still don't have an immediate solution for you, though.
