It used to copy normally, now it takes those silly breaks.

If you select CSS and Copy (Ctrl+C) it’s broken, but if you use right-click > copy it’s clean format.
//Hey, I have a solution. The Chromium developers have fixed it in the latest update .96 (it is not known when it will be stable) – until then, you just need to download Google Chrome Canary – it is fixed there. For now the stable version (with faulty CSS copying) is .95, please wait for the .96 update.
