`white-space` CSS property of clipboard data not respected when pasting in rich text editor

Thanks heaps @per1234

Can you expand a bit on examples where corruption can occur? We still have a few edge cases around nodes that we do not know how to render, but we try to ban switching to the rich editor in cases like this.

Regarding clipboard, we certainly want to improve. It is is a tough problem any exact repros here would be very helpful.
