User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:74.0) Gecko/20100101 Firefox/74.0

Steps to reproduce:

Open this PDF file in FireFox.
https://gongu.copyright.or.kr/gongu/wrt/cmmn/wrtFileDownload.do?wrtSn=9002094&fileSn=1&wrtFileTy=01

If the direct download link does not work, go to https://gongu.copyright.or.kr/gongu/wrt/wrt/view.do?wrtSn=9002094&menuNo=200030
and click the big teal download button at the centre of the page.

Select the first sentence, and right click it.

Actual results:

"새쵨하게 흐린 펈이 눈이 씬 듯하더니 눈은 아니 씤고 얼다가 만 비가 추윁추윁 내리는 꾠이었다." is copied. See the attached screenshot. Top is FireFox, and bottom is Chrome.

Expected results:

"새침하게 흐린 품이 눈이 올 듯하더니 눈은 아니 오고 얼다가 만 비가 추
적추적 내리는 날이었다." should be copied, as is when doing the same thing in Chrome.

This bug is still present.
For example if I copy the first line, with Firefox I get:
운섘 잋은꾠
when I get:
운수 좋은날
in Acrobat DC.
:Snuffleupagus, do you have an idea here ?
