This is a known issue. It is open on the Android Open Source Project Issue Tracker:

https://code.google.com/p/android/issues/detail?id=175595

The workaround described by the Android project member is:

Workaround: Try rendering with M preview using AS v1.3 preview.

Another way to workaround this issue is to replace your android.support.design.widget.CoordinatorLayout with a FrameLayout when you want to edit it in the visual design editor, make your changes to the layout and then change it back to a CoordinatorLayout when you are finished.
