14814	Using Firefox Nightly and switching between source / normal mode adds a newline to <pre> blocks	SphinxK		"== Steps to reproduce ==

1. Use http://nightly.ckeditor.com to type some text
2. Switch to source mode and add <pre>foo bar</pre>
3. Switch back to visual mode
4. Switch again between source and visual mode

== Expected result ==

No side effects from switching between modes

== Actual result ==

A newline is added right after the opening <pre ...> tag, each switch adds another newline.

== Other details (browser, OS, CKEditor version, installed plugins) ==
I reproduce this with Firefox Nightly only and on MDN (e.g. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_objects/Map/set$edit ).

I'm sorry I cannot go further analyzing the issue with my knowledge."	Bug	closed	Normal		UI : Source View	4.5.11	fixed
