End-line characters are getting ignored when copy text from editor for both repository as well as snippet.

Steps to reproduce

2. Copy some text from a file or click on copy source on clipboard (a copy sign present at uppermost right hand side of the text editor).
3. Paste it in any text editor.

Example Project

Source file: https://gitlab.com/snippets/1855557

Pasted text should be as it's of copied data (no end-line characters should be ignored).
