Intellij IDEA 13 code completion popup disappears on documentation popup appearing

Question

Such behavior was not all the time. Previously it was OK, and as far as I remember documentation popup looked like a code completion popup, but now it appears like a panel and traps keyboard focus when it appears. Previously I was able to switch between code completion list elements seeing their documentation. What should I do to get normal behavior back?
