The markdown folding doesn't work consistently for "#" and "="

The markdown folding doesn't work consistently for "#" and "="

# article 1
A Paragraph.
## level 2
A Paragraph.

# article 2
A Paragraph.

When I click the fold icon at the left of article one, I expect it to fold all lines till article 2. Current behavior is to fold all lines till level 2.

However, this works as expected.

article 1
======
A Paragraph.
level 2
--------
A Paragraph.

article 2
======
A Paragraph.

Congratulations for an extremely useful package - thank you!

However, I have also observed the behaviour described in #2973 - it is very unfortunate because for our use case it really degrades the user experience of an otherwise excellent tool.

I can add that:

# heading 1
## heading 2
something
### heading 3
#### heading4
other

will display folding icons at headings 1, 3 and 4 which do nothing at all. I might try to fix this myself if given some pointers. Many thanks in advance!

Thanks for suggestion of help, and for poking this issue.
Turned out it was very easy to fix #3841
