Exported LibreOffice Writer's Korean Old Hangul PDF

In Writer and Presentation

Noto Sans font's Some Old Hangul syllables have abnormal shown in exported PDFs

Example)
옛 한글 테스트(Old Hangul Syllable Text Test)
ᄀᆞᆯ 가람 강(江)
ᄃᆞᆯ달
제주어(濟州語, Jeju-eo Test) 
ᄒᆞᆫ저 옵서예 - 안녕하세요 
ᄆᆞᆷ국- 몸국 
月ᅌᅯᇙ印ᅙᅵᆫ千쳔江가ᇰ - (Middle Korean text)

only, ᄆᆞᆷ국 is likely shown  ᄆᆞㅁ 국 - 몸국 in exported PDF.

I think Some Old Korean Hangul Syllable in exported PDF is abnormally shown. 

Steps to reproduce:
 1. Open a Writer or Impress file
 2. Set the font to Noto Sans CJK KR Regular
 3. Write some Old Hangul Syllables.
 4. Export to PDF


Below is Old Hangul Syllable table link.
If you check the old Hangul Syllables, should check the link.

A new major release of LibreOffice is available since this bug was reported.
Could you please try to reproduce it with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the bug is still present in the latest version.

Original LibreOffice Writer's Korean Old Hangul file screenshot (LO 4.0)

When looking at attachment 153475 [details], in LO 4.0 and preceding versions the first character looks similarly bad as in the current PDF export (except 3.3, where it still looked fine in Writer), attaching screenshot. Not sure if the information is useful, but that changed when HarfBuzz was enabled with the following commit.

"Enable HarfBuzz by default"

PDF export crashed before the following fix in 4.4:

Comment 19 Aron Budea 2020-10-16 13:15:36 UTC
Confirmed with the ODT sample in LO 7.1.0.0.alpha0+ (6aa831bf46282d3df8b5f214abed7428bd4bd001), 4.4.0.3 / Ubuntu.
