Steps to reproduce the problem:
1. Open CKeditor, type in a lot of things
2. Switch to source code mode
3. And the scrollbar is there and it completely kills the browser if there are more html content

What is the expected behavior?

What went wrong?
When I click on the source code button in CKeDitor, now there's a scroll bar, which was never there previously and it's also very slow and it freezes the browser if there's a lot of content.
In previous Chrome versions it worked, in other browsers it still works (but it no longer works in stable, beta and dev chrome versions). I didn't update CKeditor nowadays.

Does it occur on multiple sites: N/A

Is it a problem with a plugin? N/A 

Did this work before? Yes In all previous Chrome versions.

Does this work in other browsers? Yes
