Source editor copy/paste is unpredictable with disabled clipboard events
List of steps to reproduce
- open `about:config` in Firefox, search for `dom.event.clipboardevents.enabled` and turn it off
- open an article in Wikipedia
- edit the article in the source editor
- select the whole article content (ie. Ctrl+A) and copy to clipboard
- open local text editor app (gedit, mousepad, leafpad etc.), paste the copied content
- select all of the pasted content and copy it again – without any modification
- go back to Firefox
- select textarea content and paste from clipboard replacing the selected content
- preview the article
What happens?
1. The article source code pasted into a text editor has duplicated line endings. 2. Copying the unmodified article source in locally running Xorg application and pasting back into Wikipedia source editor in Firefox will produce a broken article.

What should have happened instead?
A properly formatted article when copied and pasted back with no modification into the source editor should not loose quality.
