bug during exporting to PDF/html with 'auto numbering heading' on

[retsyo]

I am using marktext-x64-win.zip ( 0.16.0-rc.2). I thought the following text

# title 1
## sub-title
### sub-sub-title
# title 2

shoud be exported as

1. title 1

1.1 sub-title

1.1.1 sub-sub-title

2. title 2

but what we get in the exported html/pdf is

title 1

1. sub-title

1.1 sub-sub-title

title 2

I'm closing this issue as this is normal and the expected behavior. Only chapters, sections, and subsections should be numbered but not the main heading.
