Line Ending Issue

Workstation is Win 10 64-bit Pro

When I copy-paste some text in Online Notepad to a different input field, every line gets padded with additional line ending symbols or space character. In example:
Original text:
"hello[\n]
world"
Pasted text:
"hello[space character][\n]
[space character]
world[space character][\n]
[space character]"
This happens when I copy-paste from 1 notepad page to another notepad page, notepad text to a website input field, notepad text to ms word, notepad text to windows notepad program

It is extremely irritating and inefficient for me to use the software! Would you mind fixing this bug asap? If not, will just use a different online notepad after a month of no update. Thanks.
