 Feel free to reopen if that z-index value is required.

 > Hmm... For me, the z-index is still required to avoid the fact that the
 editor slides between the two elements. I also tested this on a few other
 WordPress sites (all running on 4.1.1) with Safari 8.0.5 on the latest OS
 X.

 fine (even without the z-index).

 The z-index was re-added in [32100].
